I ran into a problem... I washed my grilles with alcohol before starting. i applied a good and even coat of Rustoleum Automobile Primer, which says quick drying in 15-20 mins. Its been about 40 so far and its still wet. Can it be beacause its slightly cold outside? (60 degress?) i wiped that coat off with a paper towel and tried sanding a little and applied another coat. i figure ill give it the night to dry and check in the morning. any suggestions?
