Guys I need your help-
I am painting over UV Clear with UV Clear-
I have had this happen 3 times in a row now, (on 2 different Fenders) where I am getting "Craters",
It is generally happening on the second coat-
I am using an LPH400, (silver cap) with 1-Motorgard M-30 filter and 2 Motorgard M-60 filters along with a dessicant filter at the gun-it is sanded to 600 grit, and then gone over with a red Scotchbrite-
This has happened with new UV Clear, and due to the shortage of UV Clear, I have some leftovers that are 3 and 4 years old (stored indoors), and I've used them (with new Activator)-
This last go around (after the first coat cratered), I mixed about 25% very slow SPI Reducer and sprayed 3 coats 15-20 minutes apart-it seemed better, but it's still a problem-
I'm very frustrated now (I bet I've gone through $3-400 of sandpaper on 2 Fenders) and am waiting on new UV Clear to become available-I have changed everything I can think of-no tack rag, no perfume or anything on me that is Silicone based-I use Waterborne W&G remover, and wipe it down 4-5 times with it, and let it sit overnight so that it is for sure dry-
I'm clearly out of my element, but in the past have had great results with SPI Paints and Clears-
What am I doing wrong?
