I already have your epoxy primer and urethane primer. Both are grey. I should have ordered the epoxy in black. Too late now. When I block sand it would be good to know if I sand to the epoxy. Are they slightly different colors (I have not opened them)? Should I add something to it to color, if so what?
Second question…I have your concours paint gun with 1.2, 1.4, 1.8. They specs give a range of what tip to use. Using with your gun, which tips should I use for the epoxy and Urethane? Thanks, Mike
