Re: spraying gelcoat
I've had varing luck with the preval sprayers, I only use them whem I can't get coompressed air or if its a real small job. I have been buying the touch up gravity feed spray gun at Hrbour Freight, you can get it on sale for $8.99, yes thats right, 8 dollars and 99 cents, about the cost of two prevals, I probably spend more money in acetone cleaning the gun than its worth. I only thin the gel if I have too, acetone will slow the kick, so I don't use much if I can get away with it, If its cold outside, I will warm the gel with a heat gun or hair dyer before Imix it. I use patch aid to thin the gel slightly( it helps the gel to kick) from Spectrumcolor.com. And I have found the less I thin the gel, the better results I get
