Spray it with a $15 HF purple gun, three coats. Run some acetone through the gun before ten minutes or it will kick in the gun. Set the pressure at max for the gun, heck I run it at 90 psi which is over the max. Throw it away after the day's use. Catalyze the gelcoat based on surface temperature between 1 and 2%. 1.25% almost always works fine. You can thin the gelcoat up to 15% using 50/50 MEK and styrene to help it spray.

For lots of great DIY videos on doing gelcoat, check out Andy at Boatworks Today.

People recently told me (and most of what I read on forums was discouraging like the above posters) that it was ridiculously hard to learn how to paint cars with base coat/clear coat. I watched a few videos and painted my Miata hardtop which was all ragged out and it came out nearly perfect. .


I appreciate that encouragement and am still in the decision process on this one. I bought the Evercoat for fiberglass and was thinking to just to fill in the imperfections and then cover it with vinyl. However, I just sanded my rubrail for 10+ hours so I can't believe that this small cabin is going to be much more sanding than that, especially since I have a DA and can use 60-80 grit. The problem is the mess that it's going to create but I do have a vacuum attachment and painters suits.

And I like you're comment on the HF spray gun. I've bought 4-5 of them so far!

I'll be working on other items the next 3-4 weeks but will keep you posted on the progress.
