small gelcoat repair

I have been doing small repairs with a prevalve sprayer and using patchaid to thin the gelcoat. Problem is it's either to thick to spray or if I thin it more It runs and I end up sanding through the patch because of not enough build up. Anyone have any advice. Thanks

 

Have you tried using acetone to thin the gel. You can pick up a small cheap self contained spray can at Home Depot for $3.00 or so. Get rid of the bottle that comes with it and use 2 ounce nonwax paper cups. You can get better angles with that. This has worked for me many of times. Good luck!

 

Yes, when the patchaid did not thin it enough I useed some acetone but have still had problems with it being to thin and sanding through after. I am wondering if the pre valve is just not good enough to spray gelcoat patches.

 

Use that sprayer I was talking about. Take some time spraying it. Wait a little bit between coats. And the sanding through sounds like to thin ,but also to aggressive of sand paper. What grit are you using? I mostly start off with 320 just to knock it down quick then 400, 600, and 800.

Yes I was using 320 sandpaper to knock it down. I will try one of the sprayers you are talking about. Could you tell me what brand it is. Thanks Coach

 

Went to home depot they said they dont have sprayers. Could someone tell me what kind of sprayer they would recommend to do gelcoat repairs. Thanks

 

Gel Coat Sprayers...

You can usually get a sprayer from craft stores. They use a can of compressed air.

instead of acetone to thin gelcoat for spraying, use a product called "Duratec" which makes gelcoat more like paint. The disposable gelcoat sprayer (sold by Home Depot or some paint stores) is called "Preval"

 

I have a terry bass boat with a 115 evinrude and I want to put a 9.9 beside it but I only have about 5inches on each side of the motor. Does anyone have any suggestions on how to mout this 9.9?
