I've only done a little painting, and have never worked with Permalac, but if it's properties are at all like automotive lacquer I'd try to lightly wet sand the "bumps" out with somewhat worn out 600, or finer, paper. Clean well, then re-coat. Buffing doesn't sound like the right solution for small bumps. Good luck.
