I am priming and paint my 16ft lowe aluminum boat and i need to know how much thinner to cut the paint with if any. I am new to this. I have completed the gluv-it epoxy step, by the way thanx for all the help there. Its all prep-ed for primer and paint now. I am using a pneumatic paint sprayer with a filter,dryer,regulator inline. The primer is the Ace brand primer, "rust stop" for use on all metal surfaces, the Paint will be the Ace brand as well or perhaps rustoleum. Thanks in Advance!
