- How To Spray Epoxy Primer Sealer [BMW E30 Engine Bay] Novol 2K Epoxy Primer Paint Guide | 037
In this video, I progress from the previous front support conversion by painting the engine bay in Novol 2K Epoxy Primer.
Here’s what I used in this video:
Red Scotchbrite Pads: ebay.us/txFdxe
Novol 2k Epoxy Primer: ebay.us/gmlxQY
Sealey 0.8mm Spray Gun: ebay.us/2qvsgy
150L Compressor: ebay.us/xxiVq8
Painting Mask: ebay.us/gsQzot
Poly Masking Sheets: ebay.us/e4Ms44
The engine bay on the BMW E30 was a particularly tired state with rust patches around various brackets and flaking clear coat on every surface. In doing the removable front support mod I'd even uncovered a considerable amount of bare metal around the front of the engine bay.
I was tempted to consider the engine bay as just a future project, but knowing that the Upol etch primer I'd put on to simply avoid flash rusting would likely absorb water and cause a lot of rusting in the future, I knew I wanted to apply 2k primer-sealer to a few parts so I started sanding.
When you start sanding, it invariably expands and you end up sanding things you originally intended to leave because the closer you look more more issues you see. I started with a more aggressive paper to ensure I'd taken off all the weak clear coat and any rust then worked my way up to 3M red scotchbrite pads which give a nice 800 grit style finish. Ideal for accepting a top coat.
Once I'd sanded the entire engine bay and was quite happy with the result, I turned my attention to what I'd want to be painting it with.
I decided to use a really good quality Novol Epoxy Primer, this is a proper 2k 2-part paint with hardener that is far more solid than any paint or primer you get from a can. This hardened finish is a barrier for water, and also a rust inhibitor. It can even be used as a finish coat for more utilitarian applications, but for automotive bodywork it's perfect as a direct to bare metal primer and I've had excellent results with it before.
In my experience, it also sands nicely, which is useful when you're painting the base and clear onto it. From a primer perspective, other than the inconvenience of using it, I can't see why you'd opt to use any other type of primer when doing an engine bay or any other bodywork.
One issue I had was only having access to my mini spray gun, it's a Sealey patching gun with a fine 0.8mm fluid tip nozzle. Generally considered way too fine for a primer which you more likely would want to lay down thick.
To get around this, I used 2k thinners to thin the paint down quite a bit and ensure it passed through the spraygun at the right consistency.
Before I could spray I masked the car up to prevent getting overspray everywhere, I used some poly masking sheets and plenty of tape to do that which went well.
Mixing the Novol Epoxy Primer is quite simple, it's 2 parts primer to 1 part hardener, and then add 2k thinners to get the consistency about right, in my case quite runny as I was using the 0.8mm spray gun. As a quick extra note, always make sure you're wearing the appropriate PPE painting mask when working with 2k paints. It really is bad for your lungs if you don't.
I mixed up 300ml of primer which turned out to be the perfect amount to get full coverage in the engine bay, it's rare that you don't come up short or throw some away. Once the paint was mixed correctly, I poured it into the gun and sprayed a test card outside to set the gup up correctly at about 2 bar of pressure from the compressor.
With that done, start with an inconspicuous area and begin spraying carefully. Avoid lingering on an area and getting runs, but also avoid missing bits and under spraying areas which end up drying rough to the touch.
I worked my way around the whole engine bay for two coats and ended up with a brilliant result, without any runs or missed parts. I even got that front support sprayed up nicely too outside.
There are a few bits in the finish, but knowing I'll need to flat it smooth before a colour basecoat anyway, at this stage that's no problem at all.

The epoxy VOC passes through mask easily. That's why supplied air respirators are recommended by many manufacturers. They are expensive but you can make your own setup and connect it to a full face mask such as 3M 6800 series. That protects your face/eyes too and you cover the rest of your skin appropriatly with something like a tyvec suit
Interesting idea, I will look into that, might be a worthwhile investment if we do more painting in the future.
Up to now its a fairly rare occurrence so haven't been super motivated to get fully kitted out. From my understanding these painting masks do a pretty decent job for most painting.
How are epoxy VOCs different from other paint systems like acrylic?
Love watching mate, White is my suggestion. E30s look magnificent in white.
Shane, Australia
Thank you Shane, really glad you're enjoying the vids from the other side of the world mate! 😎 Alpine White is a great suggestion, it's the proper BMW Motorsport colour for a reason. 🏁
There’s something about diamond swarchz that hits different in the light! Thinks it’s the best choice.
Absolutely, black is on my shortlist and Diamond Schwartz is a fine variation of it. I am tempted by something more unusual though... 🤔 It's a big decision!
Looking great !! big steps when the primer goes on, they you start to see big results
Yep, it's great to see something all in one colour again, even if not the final colour. 2k Epoxy primer is an impressive coating too.
Great job! Keep up the good work and I’m looking forward to the next videos 😊
Thank you Pol, glad you're enjoying the E30 series! 😃
Impressive coverage with such a small quantity of paint, and the expedient masking tape pouring spout is pure genius..
Cheers! I really do rate the Novol 2k Epoxy primer, it's amazing stuff by almost any metric. And the masking tape spout is a trick I picked up a few years back watching TH-cam videos, I thought it was genius too! 😆
And yet another great episode , this channel has to have more vieuws! Grtd
Cheers Frank! Hopefully more people will discover us. 🤞
Oh, Spanner Rash, benfidar from RV3 here, clever tape and paint pour! Never occurred to me. Brilliant!
Thank you mate! 😃 We've picked up a few good tips over the years doing this DIY painting. Let's hope I can put them to use for the next stage.
Absolutely killing it with this content! I have a real soft spot for my E30 in Atlantisblau, or Imola red/Le mans blue are my other favourites
Thanks man! 😃Yeah they look really sweet in blue, I loved the Laser Blue 318is I had years back. Definitely food for thought. 👍
Great work mate , these cars look good in any colour but a metallic blue would be stunning
Thank you Jason! Agreed they look awesome in blue. I had a Lazer Blue 318is a few years back which I adored. Popped really nice in the sun. Avus Blue wouldn't be a bad shout, love that colour.
I really like the colours they did for the design edition. The neon blue and neon green. Also, macau blue looks nice on the e30 🙂
Great build so far, looking forward to see what you decide on.
Great suggestions thank you Matt! Those neon colour edition E30s always stand out to me too, their colour combined with the special interior is very cool. Cheers 😀
I use Novol, and I can tell you, it is brilliant stuff. Better if you give it two costs or more.
Yeah blows me away how good this Novol Epoxy Primer is, impresses me every time I use it.
Would be lovely to see the car in either Malachitgrün or Alpinweiß II. Also, Diamantschwarz looks superb in nature.
Excellent suggestions Max, I particularly like Malachite Green actually, thank you 😀
Awesome work, I’m inspired to start on mine.. colours a tough choice, I’ve got the same colour as you but I’m tempted to either spray a brighter red so no log book faff, or white or black, the grey is nice too on the 325i.. good luck with whatever you choose, love the attention to detail 👌
Thank you! 😃 Yeah I'm considering the same, it's a shame it isn't a brighter red to begin with, but you can't win them all when you're looking for a project car. I do have another BMW in nicer Imola Red though so I'm tempted to do something more unusual. We'll see what I come up with. A few good options floating around in my head now. 🙃
malachite all day loooong
I do love Malachite green! I think I might slightly prefer Oxford Green II though. 🤔
I’m a big fan of Laguna green metallic code 266 . I think since your so deep into this project you can do a full respray. A color code that I’ve never really seen around is Luxor Beige metallic (219), it’s like a pink champagne color.
Oh yeah, I do love a green and Laguna is a particularly nice one. My top green is probably Oxford Green Metallic II though. When I saw an E46 M3 in that colour it was captivating.
Luxor Beige - now that's an interesting suggestion. I feel like it would suit a pre-facelift best though with chrome accents. Food for thought, Thanks for the recommendations! 😀
White ❤
Thanks Nico, you can't go wrong with Alpine White. It's the proper BMW motorsport colour too. 🏁
Estoril blue, maybe I'll go with that colour
Thanks, I do love Estoril Blue! I can't help but think it looks more right on an E36, but I will google to see an E30 in this colour. 👍
Metallic dark orange. Thats what I'm painting mine when I get it finished :) . But if it has to be a BMW color I would go with a diamond schwarz metallic.
Awesome thanks! 👍 All variations of black looks great on an E30, that's for sure. Your metallic orange idea sounds really interesting, I'm guessing you have a specific colour in mind that isn't the very nice BMW Sakhir Orange?
@@SPANNERRASH Heh I stole the color from a locally sold beer can :). Its not very far from that. A bit more "Orangy'" :)..
@@Juntasification Now that's thinking outside the box! I like your style. 😄
I would personally paint the car in the factory color. Regardless of what color you choose a great idea would be to use good quality paint and paint gun so you don't end up with a poor finish or have your paint deteriorate 5 years later (low quality paint tends to fade and crack).
The original Titian Red would no doubt be the most intelligent choice, but I'm tempted by something a bit more interesting while I have the chance! 😃
Thanks for the heads up on that, I'll make sure I pick up quality paints when it comes to the final finish. A new gun is on the cards too I think, I'll have to see what I can afford as they are not cheap to buy for a DIYer like myself.
Granitsilber metallic would be my choice
Nice colour, I was considering Lachssilber (Salmon Silver) which is similar. I really like the depth of this silver and how it appears in different lights. I'll look more into Granite Silver though. Thanks!
Looking very good, - it's obviously down to the skill of the masking expert 😀. Two questions please: were you able to check before spraying that the epoxy primer you used was compatible with the primers already on the areas you sprayed, and, secondly, how many times did you have to replenish the spray gun - I don't know the capacity of the Sealey item. Colour: I just love dark metallic blue, but I'm sure that it will look good whatever you opt for and car colours are very much a matter for individual preference of the owner. Thanks and best wishes.
Thank you George, and he does know good a trick or two when it comes to masking! 😂 Great question regarding paint compatibility. To be honest, I've recently discovered that spraying epoxy primer directly onto etch primer can be a bad idea as the acids in the etch can cause a paint reaction with the epoxy. It's recommended to go directly to bare metal with 2k epoxy, but its perfectly happy to go over previous paint finishes that are well sanded down and keyed to accept a new coat. It's bloody remarkable stuff to be honest.
I haven't had issues before, but I was glad to find out about potential issues with etch. With that in mind, I really took down the Upol etch primer I'd put on in areas with sand paper. I also knew the etch primer had been on for a good while so any acids had diminished. I'm pleased to report there are no issues so far and it's fully cured now. As for the zinc primer which is under in some areas, its very inert stuff that so I'm less concerned.
To be honest, I had to top up the patching gun quite a few times. I didn't count but probably 5-6 times ish. I do like to avoid brimming the pot though as it tends to start pouring out of the breather, down the gun and over your hand - which is really annoying! 😏
Thanks for the suggestion of dark metallic blue, seems most people are voting blue right now. It's quite tempting as I've got very find memories of a Lazur Blau E30 318is I had years back. Cheers! 👍
Looking good now mate. Just a quick tip, all the epoxy primers I have used to date have a special thinner, totally different chemical to normal 2K thinner. Don't know whether it will cause any issues further down the line, but if you use any more of the Novol product, which is excellent by the way, it would be best to get some of their epoxy thinners to go with it. I know how you feel about the final colour, it is always tempting to do a colour change when the car is stripped as far as yours. Is it Zinnober red originally? I have an E46 in Imola, it looks great in bright sunshine but a bit drab when it is cloudy. Anyway, you have great attention to detail so it will turn out great I'm sure.
Thank you Bob, appreciate the heads up about the thinner I used too! I wasn't aware it was a totally different chemical, but I did know it wasn't quite the right one for this. At least I didn't use gun wash, right? 😆
I think I've got away with it this time, so far so good. It seems to have cured beautifully and appears ready to sand.
I'll make sure I use the right products together when it comes to base and clear, don't worry.
You're absolutely right, it's not every day you get to paint a car in any colour you like - it's quite an overwhelming decision really as there are so many colours I like!
It's originally Titian Red (Tizianrot), a very dark flat red. I also have an E46 in Imola Red, and Titian Red seems really drab and dull compared to that.
I think if I was putting this car back to anything like standard I'd be motivated to keep it the original colour.
But as I'm going to be making it my own "restomod" type thing, I think picking a new colour that I love is the way to go. But we'll see, my mind is all over the place about it currently. 😅
Excelent job. Now the engine bay looks at least clean, since you have the rest masked, it's wise to unify operations that can be done at the same time - colorize... 😉 Well, the choice is almost infinite, be sure to paint with some compound that reflects enough light with the specific wavelenght for the eyes to recognize. You certainly don't want it transparent or disaster will come early. Can you imagine having a glass car? 😂There would be an accident really quickly.
Choose wisely the color, as it's going to be probably the same for exteriors. I would say not to white, not too black. One gets dirty fast, the other sucks in a lot of sun heat. The choice is your preference. Take a picture of the car and then (if you have photoshop) try some colors to see.. It might help. Cheers, once you get in the inspiration and start going, never stop!
Hahaa I think we're a few years away from transparent or active-camouflage car paints. It would be very cool, although probably the opposite of spectacular as it couldn't be seen. 😂
Great idea to Photoshop some colours, it will likely help me in the decision process. Cheers!
Mauritius Blue
Nice suggestion Chris! I once saw an E34 M5 in Mauritius Blue at a show, and it definitely caught my eye. A stunning colour in the sun. Thanks 👌
Bmw technoviolet would be nice, or malachite Green, which is period correct for this car
Cheers Logan, both amazing colours! Technoviolet is one of my faves, so cool.
Paint: imola rot. nice red color :)
Now you're talking - Imola Red. I think it's my favourite BMW red of all time, the right amount of depth and the perfect hue, not too orange and not too pink. This is definitely on my shortlist. The only problem is I already have an Imola Red E46! 😂 Cheers
@@SPANNERRASH More is better than less! 😃
I'm big blue fan, but...
It't needs to be something special
Darker yellow or purple then? Maybe you can find something from BMW color list or maybe from Porche color list?
Blacks, blues, whites are boring for this project, in my opinion.
@@veikovrklv Haha a matching pair could be very cool, but I think I'm leaning towards something a bit different with the E30.
I agree, something a bit more special and unusual could be good.
Porsche colours are certainly an interesting thought.
Porsche Speed Yellow could be cool, but I feel it would look a bit better on E30 M3 body. Porsche Violet seems interesting!
I will have a hunt around online for some other ideas, I don't know my Porsche paint colours that well. 👍
@@SPANNERRASH JimmyO Dubai video, there was interesting colored E30 th-cam.com/video/uv400rBsHgs/w-d-xo.html
Met slate grey
Possibly a bit safe, but always looks tidy. A Dolphin Grey E30 always looks sweet. Cheers for the suggestion!
What happens if you put a layer of clear coat?
You end up with a shiny grey engine bay.
I'd recommend keying up the epoxy primer finish with a scotch pad up to a fine 800 grit finish before spraying clear on, should work wonderfully.
The problem you might have though if you wanted to do this with a whole car to have a light grey car is the colour of the primer isn't as consistent as proper base colour.
That's if I've understood your intentions. 😄
im about to do the same and my color would be BMW color Le-Mans Blue
Love Le Mans Blue, particularly good looking on the E90 E92 series cars, I bet it would look gorgeous on an E30 too. I hope your paint job goes well! 👍
So many people are suggesting blue colours, they seem to be the most popular. I had a really nice Laser Blue 318is E30 a few years ago which I loved. I feel like this E30 should be different though, otherwise I'd be keener on a blue option. We will see!
@@SPANNERRASHIt was mentioned somewhere that e30s need a lighter colour to show the lines which I think is true. I would go for a silver or Calypsorot Metallic otherwise.
Black?
Very tempting with black, Marios. Always looks stunning. I could even do it in single stage like I do some parts I paint. It always comes out great and imperfections can be flat and polished to absolute perfection easily, even if the actual spray job I do isn't professional quality. It's definitely something I'm considering. 😃
