Spray on hotcoat

Has anyone ever tried to spray on hotcoat similar to using a gelcoat gun?

I was thinking about it on the weekend and cant think of a good reason not to?

the board would end up being a lot stronger as there would be more even coverage and a lot less material used to fill the weave… might also cut down on the sanding side of things…

thoughts?

there has been some talk about it here before not sure on the result if any…it all sounds good on paper til you try it…crazy overspray more fumes being atomized more clean up including yourself and shop …mekp and styrene are some nasty chemicals to be atomizing …I would try it though…good or bad then youl no for sure…just dont try it in your kitchen

Howzit riffraff, Too much trouble cleaning the sprayer and acetone is not good for the seals in the spray gun. When I was a boat gelcoat repair guy our sprayers were always needing new seals and the guys didn’t always clean them good so the next person using the gun usually had to work with it to get it to spray correctly. If you do your hot coats right with a brush you won’t have an uneven or to thick layer of resin to sand. Aloha,Kokua

the simple answer…more trouble than it’s worth.

i know a guy who does auto body repair and restoration. when he made his first board, he initially thought it would be easier to spray his hotcoat. the more he thought about it, the more he realized what a colossal pain in the a$$ it would have been.

brush the hotcoat.

if you’ve got the spray equipment, and want a nice result with minimal sanding/polishing, spray a urethane finish.

it takes me five minutes to do a hot coat most of that time is spent on cleaning my brush…quik and painless “just walk away”

You would have to use a pressure pot with a liner and I guess you would have to flush the the hoses with alcohol before the epoxy sets up.

It would be worth it if you had a bunch of boards to do.
