Hello everyone
I need to do some gelcoat repairs on one of my boats. I tried a preval and it turned out like garbage. The thick gelcoat doesn't go through them very well and if you thin it down a lot it lays down very thin, and you end up needing tons of those sprayers. Besides, if you run acetone through them to clean them they get screwed up, and don't work like they were when new. When new they are alright, but I have to keep buying them and I decided its time for a good gun, since I restore a boat every year, and its something that would see some good use. Can anyone recommend a good hvlp gun for gelcoat? I was looking at the 3m accuspray, and I kind of like the idea, but any other good ones besides that?
One more thing. When I preval sprayed a test area last time, the gelcoat stayed tacky, despite me adding wax additive. a week later, it rained, and the test section turned white and absorbed water. What the heck did I do wrong?
Thanks
