Acetone for thinning gelcoat for spray??????

[harmuthmarine]

Acetone works ok you have to spray it quick or it gets thick again Mini Craft makes a thinner thats awsome and i think ive used MEK once not MEKP and i always mix my gel at 2% dont cut the gel any more the 15% or the stuff wont harden. As far as a tip size i use a 2 in my touch up gun and a 2.3 in my big gunn and crank the presure up till it comes out good i think its like 40 psi the best gun i found were guns i bought at LBI in Groton CT
