Hi, 
 
Can i add some product, for example acetone, to thin the epoxy tooling gelcoat a little bit so i can spray it?
I know it could not be "thinned" too much but I have a spray gun with tips ranging from 1 to 4.7 mm.
I had a try with my 4.7mm nozzle, and gelcoat seems to be just a little too thick to spray.
