I"m gonna try to get some epoxy and 2k(first time shooting this) sprayed this weekend on my 69 firebird project. It is supposed to be in the mid 80"s-90's this weekend. I have some slow reducer. Do I need to use it and how much do I add (usually mix a quart at a time). How many coats of 2k should I put on and what tip? Safety precautions with the 2k (Gonna use my fresh air mask for the first time)? I already blocked out the first 2 coats of epoxy and filled most of the low spots with Rage Gold. Thanks.
