2k Primer spray problem
I always used 1 K [rimer, but I used this time 2 K primer: ratio 1 part: 1 part catalyst. The primer dried extremely fast at first layer, but second layer it makes some king of garnule and powder once dried... when you toiuch it, the primer become a kind of yellow powder at the surface, almost like primer dried before reaching the metal... I need to wet sand it now grrrrr.... what did I do wrong?
I suspect my spray gun setting or can do I need (or can) add more reducer??
