Wrinkling Paint

After sanding paint finish off metal surface, priming the metal surface, then spraying on initial coat of lacquer all was smooth and fine. This coat was wet-sanded then a second coat applied. The second coat began wrinkling in spots.

What would cause the wrinkling in spots? Now unable to sand smooth and reapply without the same results.

The problem you are having is that the 1st coat of paint is already dried to a point where it won't accept paint probably for another 2-3 days. What you should do to fix it is sand it back down put your first coat on and don't wait so long before you apply a second coat and remember 2 light coats with 10 min. between coats is better that one heavy thick coat.

Good Luck,
