Hey Blue Heron I assume since you are thinning the gel coat you are using a tip around the 1.5 size? Have you had any luck spraying unthinned gel coat out of a larger tip gravity gun like 2.3 size? I have a few other mold projects I would like to tackle if I can get this one to come out right so the money on the gun wouldn't be a loss but if a $30 gun works as good as the $120 cup gun I would rather save the extra cash.
I plan on ordering my supplies from us composites seems like they have good prices. I am going to use vinylester for the layup if that matters.
