- In todays video we cover some final sanding of the TotalBoat polyester fairing compound and spraying the first box with TotalBoat gelcoat with wax. Please Subscribe!!
In the video I am using a "cheap" spray gun I bought off amazon. You need a 2.5 nozzle to spray gelcoat. At my shop I have very expensive spray guns but you DONT need that! Just be sure to set yourself up for success!! Please check out my NEW video that focuses on ONLY this cup gun and spraying gelcoat.

Success! Looks great, thanks Will!
Will sent you a PM need help please
What size compressor are you using? Sorry if I missed that in a previous video.
at the time of this video it was a small rolling job site compressor. I now
have a large 200 gallon compressor.
@@HoldFastMarine Thanks, I was wondering if a 10 Gallon Rolling Compressor might do the trick.
Cool stuff but fuk this i paint cars and do body work and this shit is way to complicated with way to many chemicals and mixes if i need to spray a boat ill just get some single stage and add a shit load of flex additive screw this
Yeah lol. Single stage is good but doesn’t last very long. Once you do it a few times it gets pretty easy!
Great video, thanks! I'm a DIYer and have tried spraying gelcoat with varying degrees of success over the years. There is an additive/thinner called Duratec that I really like.
The tip on removing the filter is gold. Can't wait to try that!
Funny story: I sprayed a part one evening--it was cold in the garage and the gelcoat didn't want to kick. I warmed the kitchen oven to just over 100 degrees, turned it off and put the part in there overnight. Worked like magic; but, when the wife and kids came into the kitchen for breakfast the next morning I was not a popular man. Needless to say, I haven't done that again. Haha.
Funny sidenote: Since this video is for a "Dorade Box" I thought would share that I've actually done a bit of sailing on Dorade. Great program.
Great video... Thanks for the information.
Where is your shop located? wanna do a small ice box lid container repair ?
Shop is in hubbardston mass. And if you want to ship it to me I’ll do the job.
You didn't mention if you thinned the gelcoat to spray.
Hello! I did not thin the gel at all. Truth be told I’ve never thinned gelcoat.
I always thin with spectrum patch aid to get rid of orange peel as well as give faster or slower cure depending on which patch aid I choose.
I guess they mean they reduce it all the other mumbo jumbo is pointless
Looked like you mixed it with half the required hardener (4x16=32?). How did it turn out?
I had my first experience wit gel coat (Evercoat One Coat - no wax needed) this week and even though I mixed it correctly it’s not curing. I wish I watched this first because you go to great effort to maintain room temp. I’m in CT and my garage was 62F during the first 24 hours. I have it up to 72F now but not sure it’s going to fully cure. Very upsetting.
Gelcoat will not cure without wax, or putting pva over the top. Any polyester based material needs to have either wax, or pva added post spray. I always use the required amount of mekp, either by weight or drops.
I have a cheap Amazon spray gun and I am in the process of redoing my boat. Could I add color to the gelcoat when spraying it? If so could you do a video on it or give me some direction on how to do it?
Colored gelcoat is no different than white. Why not just buy pre mixed colored gelcoat? I suggest you watch my other spray video that gets into more detail.
Thanks man, I will be sure to watch them. I knew to this so I'm learning.@@HoldFastMarine
my hvlp has a 2.0 mm tip. do you think i can get away with using that?
Give it a try! I’d turn the air pressure up a little to make sure
Wtf is zylene you mean paint thinner??
Nope I mean xylene. Paint thinner is different.
Hey what gun could. I use to spry gelcoat am about to paint my boat
Are you painting your boat or gel coating you me boat?
@@HoldFastMarine well we just got down with the inside and it’s primed already now we just need to paint it with wire gelcoat
How much air pressure do you have at the gun> 35?
Yeah pretty close to that.
Nice video good info , Im thinking of buying a Gelcoat & Resin G830 gun cheap for one first and only project will that get me by ? Thanks
Give it a try!
In the vidio you said the gelcoat needed 14 to 16 drops of MEKP per Oz. You chose to use 16 but then you said that you had 4 Oz. of Gelcoat so you would need 32 drops of MEKP.... wouldn't it be 64 drops?
Maybe?
Be nice to know what aircompessor for the job on a budget.
You can get a 60 gallon dewalt air compressor for about 800$. That’s as budget as your gonna get. Nothing less than a 60 gallon.
Okay 60 gallon. Does the horse power or psi matter? Psi to cfm conversion would be great too. Thank you!!
@@Shokenryu it does matter. You have to do a little work yourself bud. Always follow the manufacturers instructions when spraying.
Thanks for the great video. So many youtubers film hours of sanding, prep time, etc., when we viewers want to see the "meat" of the videos. Thank you for speeding up those portions. We're here to learn something. Not watch someone else to the tedious tasks.
Thanks!
Great channel thank you! I’m in the process of spraying gelcoat layers. How many layers of gel coat do you recommend before sanding? I’m afraid I might send through. I’m spraying an entire boat 26 foot.They say 22 miles thick but how do you measure that when doing layers?
Well it is frustrating when someone says “this thick” but give you no reference. When your spraying it will be thick, make sure you use laminating gelcoat! Two coats of laminating and one coat of finishing should do the trick for you. You have a lot of sanding in your future my friend!!!
I'm using this same spray gun woth the 2.5mm tip and the gelcoat doesn't come out at all. What psi are you running your compresser at? I'm got it regulated at at 80 psi on the getting about 40-60psi when it drops and still nothing. Any advice?
Did you take the screen filter out? Watch my other spraying gelcoat video and I explain where the screen is.
@Hold Fast Marine -DIY tips and tricks- yes, I took the screen off as well. The gelcoat I'm using is from fgci with wax. Not sure if that makes a difference.
4 oz 32 drops?
Just a simple verbal error while filming. I always measure by volume not by drops.
Hi,just wondering if I can draw or design using gel coat paint with the airbrush??thanks
Hello. An airbrush won’t shoot gelcoat. And I’ve tried many times. It’s just too thick.
Hello, so if you use gelcoat with wax, how many coat can you spray. Do you have a video explaining gelcoat with wax and without? Kinda confuse lol
Gelcoat with wax needs to be sanded between coats. Without wax is a laminating gelcoat and can be applied several times. But you need to cure the unwaxed gelcoat with either pva or a final coat of gel with wax. Check out my other spray video
pick up your tools you are a disgrace what did that socket ever do to you
Lol OKKKKKKK
Fuck!at least gob of camera!!!!56 seconds in
What?
It looks like you’re spitting on camera 😅
Do you have to spray a clear over it or does the gel coat not need it?
Negative, no clear coat needed. You do have to wet sand and buff it to get it to shine.
Would a 1.7 work ?
Ya know I’m not 100% confident it would. I’ve never used smaller than a 2, if you went with one that small I’d reduce the gelcoat with some styrene
Did you try the cricket with gelcoat?
are you talking about a dump gun?
@@HoldFastMarine
I don't know what a dump gun is. I was thinking of spraying gelcoat for a boat.
Well I don’t know what the cricket is lol. A dump gun is a spray gun made specific gelcoat. They start at around 200$
@@HoldFastMarine yea I'm ok 😆. Critter paint gun. Cricket must be a smaller version. Sorry. So have you tried the critter to spray gelcoat?
@@redwood1957 I have never tried one, but did google it. The nozzle is very small. I don't think you'd it to spray.
So I guess it’s ok to spray gel coat without a thinner?
It sure is!
Thinner for gelcoat? U from Mars?
@@vasantuchil5302 you much be from not this solar system cause it’s perfectly normal to thin gelcoat for spraying in a gun…….
@@ants00
Not advisable at all Rossi. Check it out. Gelcoat is a special formulation & viscosity is maintained by mfrrs for ease of application, always. By thinning it you are compromising quality as thinner will react in a haphazard manner. Earthling if course 🙏🙏🙏
@@vasantuchil5302 I literally talked to them on the phone before I did my work. They said it’s fine and done all the time. I think the people who make it are to trust. You HAVE TO buy it without wax and apply the a coating at the end to cure it. If you don’t then the job is done wrong. If you add the wrong about of styrene(which is all you can use to thin, not acetone) then it’s done wrong. So there’s a lot to do right to make sure it’s done correctly
Hello, thanks for your video. Have you ever had any experience using styrene? Looking to thin out my gelcoat and spray it. Trying to shoot it thin and without orange peel. Any advice?
I have. Be careful with it! sorry for the late response btw
really, did you really spit across the field of view... not cool at all 🤢🤮
Awe.
