ok here goes. this is what we did on the hood.
It is ProForm 2K urethane primer surfacer. The mixing ratio is 4 parts primer to 1 part activator. The final sanding before priming was done with 220 grit. The primer itself was put on in 2 stages. starting around noon, first we sprayed a fairly wet coat, with a flash time of about 15 minutes, and then sprayed a little bit lighter coat. This was sanded with 220 then 320 9 hours later. Second stage of priming occured 2 hours later, spraying one coat, flashed for 15 minutes, and sprayed another coat. That was sanded with 320, 400, then 600 the next afternoon. The basecoat of color is Dupont Chromabase GM black (year 2000) using 7175S basemaker mid-temp activator-reducer. The mixing ratio is 1:1. Sprayed 1 coat, let it flash 10-15 minutes, sprayed 2nd coat, let it flash 10-15 minutes, and sprayed a 3rd coat. (they were all fairly light coats) The clear is Dupont ChromaClear 7500S, with 7570S reducer, and 7525 activator, with a mixing ratio of 8 parts clear to 2 parts activator to 1 part reducer. After spraying the base I waited 1/2 hour to spray the clear on, applying one coat, letting flash for 15 minutes, and then spraying the 2nd coat. That is all the spraying I did.
