i want to primer my 53 buick, and use ppg dp 90 primer on the steel then use k 36 for final sanding, but i was reading through ppg's book and it said when using dp 90 you can prime the stel then sray your k36 on top within the same working day without scuffing the surface. however if you leave the dp 90 for mor than a working day you have to spray a coat of dp 90 and then your k36. my buddy did this and is having a nightmare his paint is blistering, and now im nervous about using dp 90 on my car. did this happenn because the dp 90 was still giving of fumes and was not cured? can i use k36 on the bare properly cleaned metal, after all it is a urethane. im scared about the epoxey stuff now. my buddy says that the dp90 takes about 2 to 3 days to cure using dp 402 catalyst
