I have tried to spray gelcoat out of an automotive paint gun (Sharp Model 75) and it was very slow even with the gelcoat thinned past what was recommended. What does everyone think about using a texture paint gun like what you would use for a textured house celing paint? I was looking at this one http://www.harborfreight.com/cpi/cta...temnumber=2471 and it has 4,6, and 8mm tips. The Gelcoat dump gun that I was looking at says to use a 1/4" (6.3MM) tip for metalflake gelcoat. Looks to me like it would be a good solution for trying to spray gelcoat on a buget.
