Great video mate...literally the only one I've found on 447, glad I found it..will be using this along with por 15 when I do corrosion treatment on my m3
Awesome, I was looking for a video just like this when I was shopping around for the right stuff to use. Hopefully this one helps people out! 447 is great stuff, hope you have a good experience with it too mate. 😁
A horrible task but I'm sure that you will reap the benefits in the long run as the car is a 'keeper'. I'm sure that you would love to have a car lift (so would I) or a rotisserie to enable you to get better access and room for spraying, but you are doing a great job with what you have available.
Thank you, George! It's definitely worth the effort, things are so keen to rust around here that it'd be playing on my mind constantly. You're absolutely right, a lift would be a godsend! I've thought about it a lot but there's just nowhere near enough headroom inside my garage to make it possible. You can get those scissor lifts which avoid having posts, which I was tempted by. But thinking about it I realised that the mechanism beneath the car would be in the way of any underside work I was trying to do anyway. A rotisserie would have been excellent too, but again comes down to space. If I'd known how much work I would be doing under the car though I might have thought more seriously about that though... 😂
Great job mate. I would’ve probably painted body colour or black over the stone chip, as it might stand out a bit against bright red bodywork. Awesome job though.
Thanks Logan! Definitely a good thought, ideally I would have painted it body colour but I'm still a bit torn as to what colour I want to paint the car. Whether its back to its original Titian Red, or something different. As standard from the factory its a kind of beige stone chip underneath, but with black over the top in wheel wells. I thought grey might look a bit more professional as you often see folk slapping black waxoyl straight over rust and I wanted it to look a bit more obvious that its a "proper" job that's been done. I suspect after a while with some road grime the grey will look a bit more natural, although it is pretty bright and stark right now! Not that people will be looking underneath too much, I hope! 😅
Hi, very professionally made video, sorry for the late "tip" for this underseal. Dinitrol is a great company regarding the underbody protection. If you want, check the " Gerhard Holzknecht KFZ Service "channel, it's an Austrian guy that does underbody protection for a living and uses Dinitrol products, speaks german but most of the videos are self explanatory. In the video, your underbody gun has a variable nozzle i.e you rotate it and you define the "texture" of your finish by rotating it, it can be very coarse or fine, you got a very pleasing finish. You can try weld-through primers as primary inner rust protection from Upol and Novol (novol has its specific red color) which is followed by Dinitrol ML(ger. Kriechöl)-rust penetrating oil and Dinitrol 1000-cavity wax . Cheers 🍻
Awesome thank you Marin, I really appreciate the recommendation there I will check that guy's channel out. You're blowing my mind with what you say about the nozzle rotation, it looks to me like it's just a round thing that screws on and off, but you could well be correct with what you say about it changing the spray pattern! I should have a play around with that and find out next time! I'm pretty pleased with how it came out for a first try. Thank you for the tip on weld-through primers too, I wondered what the red primer was I'd seen others using. I'll definitely be adding that to my shopping list. 👍
@@SPANNERRASH You are welcome, hope everyone who comes across your videos can learn something new. "Restore It " is also in the process of restoring an E30 325i sport, but he is going on another route(check his channel too). I have Einhell underseal gun, it has a fixed nozzle, don't buy that. I clean it with dunking the aluminium tube inside the bottle of Nitro thinner and spraying it on cardboard, works flawlessly :D .
@@Ezio11 I hope so too, I like to make the video I wanted to find for myself when researching to do a job. Ahh yes I am already a "Restore It" fan actually. I've watched his channel for some years now. I think he is much more detail orientated than I am which I admire. Cleaning the Dinitrol out of the schutz gun when it clogs up is the most frustrating thing ever. Its such a stubborn coating I almost threw the gun away rather than clean it. 🤣
As in multiple coats of the same product? I think it's a one good coat type thing but I suspect if you put a second on it wouldn't do any harm. Other than being overly thick. I'd recommend checking out the spec sheet for the product.
The inner and outer arch are spot welded together and I injected cavity wax from the inside od the boot. I'm planning to to pack the arch with seam sealer, in the wheel well. But I haven't done that yet as I'm planning to roll the arches a bit, and the car isn't yet on the road in the meantime so I'll wait before I seal them properly. Originally BMW had a thick bead of a seam sealer in there. Hope that helps!
The wax is better than you think, it comes our very thin and goes into places you wouldn't get a product like 447. It then firms up and stays as a water repelling protection. I suspect it will need topping up every so often but the type of use this car is going to see from now on (fair weather mostly) I think it will hang around for a while. I suppose we will find out. 😄
Hi John, the grey Dinitrol 447 definitely doesn't match BMW's factory beige undercoat. I think many have tried to get an exact match and failed. If I recall Upol Gravitex might be a close one (check that as I might be remembering wrong). As I'm doing the entire underside of this E30, and its going to be a "restomod" style build, I wasn't that precious about it looking factory, so I just went with the one I got the best recommendations for in terms of its protection. Hope that helps!
@SPANNER RASH thanks for that reply I will search the net for it Would like it original but not a show car just 20yr old this year I want it back to a decent standard. Thanks your project looks good so far.
Hi Ciaran, its a strange stuff, its over-paintable so its outer shell feels quite solid, but its also thick and rubbery/elasticated under pressure. Needless to say, it's highly reviewed and seems like it will work really well. You don't want to get it on things it shouldn't be on, because getting it off would be an absolute mission.
Turned out I only used around half a bottle of ML. Hope it keeps because I've held on to it, to do the front chassis rails and cavities when I get to that part of the project.
Was there any reasoning why you went with 447 which is a stone chip protection instead of a dinitrol 4942? looking to do this to my own car and can't make any sense of all the products.
Hi mate, I did quite a bit of reading and got some recommendations before pulling the trigger on the Dinitrol 447. I'm pretty happy with the result! the 447 is a thick, durable and solid underbody protection, similar to what the OEMs apply to their cars in the factory to protect from grit and salt throughout the life of the vehicle. The 4942 you're looking at is more of a wax coating that you'd apply on top of that for extra protection. I may end up applying something like that under the car every few years to really protect it from the elements. Hope that helps! 👍
Looked into 447 based on your excellent video. Do you know/recommend it via aerosol? Seems it’s only shultz compressor use in grey? Great video excellent work
Cheers! The Dinitrol 447 is great stuff, although I've never tried it from an aerosol can to be honest. I imagine just the same but you might want quite a few cans.
Nice work bud. Just been through your welding videos. Gives me inspiration to sort the rusty e30 in the garage!
Cheers Alex, I'm figuring it out as I go, glad its encouraging you to get stuck in on your own car.

Good job. I had cavity wax pour out too... stuck some containers under each hole I applied it to.
Thanks, and good idea, I should have done the same. A lot more came out than I was expecting to be honest.

Not that people will be looking underneath too much, I hope! 😅
IMHO the best is Wurth. Use hot water and let the cans sit in it before use. Also give the cans a REALLY good shake before you use the cans.
Nice, I've not tried any of the Wurth products but I'll look those up. Thanks for the recommendation. 👍
Can I ask how many cans of 447 for the complete underside and wheel arches please? Thanks
I'd recommend 8 in total, pretty sure that's what I used in the end. 😃

After dinitrol 447 do we need to coat dinitrol 447 or undercoating is done ?
As in multiple coats of the same product? I think it's a one good coat type thing but I suspect if you put a second on it wouldn't do any harm. Other than being overly thick. I'd recommend checking out the spec sheet for the product.
About to do the same thing. But what did you do where the inner and outer wheel arch meet? Did you apply seam sealer there?
The inner and outer arch are spot welded together and I injected cavity wax from the inside od the boot. I'm planning to to pack the arch with seam sealer, in the wheel well. But I haven't done that yet as I'm planning to roll the arches a bit, and the car isn't yet on the road in the meantime so I'll wait before I seal them properly. Originally BMW had a thick bead of a seam sealer in there. Hope that helps!
whats the point of cavity wax? it will be gone in 1 season. 447 i think would be better for cavities
The wax is better than you think, it comes our very thin and goes into places you wouldn't get a product like 447. It then firms up and stays as a water repelling protection.
I suspect it will need topping up every so often but the type of use this car is going to see from now on (fair weather mostly) I think it will hang around for a while.
I suppose we will find out. 😄
Is that 447 bmw colour from new iam just away to start a rear restoration on my 2004 E46 and it looks beige colour. ?

Thank you @@johncoutts9237, best of luck with your underside protection, hope it works out nicely.
Is dinitrol a rubberised underseal?
Hi Ciaran, its a strange stuff, its over-paintable so its outer shell feels quite solid, but its also thick and rubbery/elasticated under pressure. Needless to say, it's highly reviewed and seems like it will work really well.
You don't want to get it on things it shouldn't be on, because getting it off would be an absolute mission.
So did you only use one bottle of ml
Turned out I only used around half a bottle of ML. Hope it keeps because I've held on to it, to do the front chassis rails and cavities when I get to that part of the project.
Mate jest buy vaupel fgr 3000 Gun with hook Wand and cavity nozzle then you will see ML smoking
Interesting I will look that gun up, thanks for the recommendation! 😃

Thanks, it did! Information on which product is made for what application is quite scars from dinitrol.
@@details2378 Indeed, it can be pretty mind boggling. They're missing a trick with that...
