I almost botched a paint job recently due to solvent pop. Laid down 3 clear coats exactly within window of doing base coat. Bubbles soon appeared, collapsing into tiny craters. Learned it's not an exact science regarding time intervals. Blocked the clear with 600 grit to both remove craters and orange peal in clear. Laid down 4 more coats of clear without issue. The depth, and gloss were spectacular. Later learned that's what custom painters call, flow coating. Used an orbital palm sander to 8000 grit Trizac, followed by a Flex buffer with Sonax polish. Net result is show stopping.
