I’m having a problem with the finish on a pair of speakers I’m restoring.
I re-veneered in mahogany and put two coats of spray satin lacquer on them. I sanded between the first two coats.
When I sanded again to prep for a third coat, I sanded all the lacquer gently with 400 grit sandpaper, but I also had to sand a couple of tiny spots a little more to remove something I saw in the finish. Then I applied a third coat of lacquer.
When the lacquer dried and I looked over the finish, the tiny spots that I had sanded a little more had tiny white specs in them. I assumed that this was because I didn’t remove the dried, sanded, lacquer-dust good enough before putting the next coat on. So I sanded those areas again, and spread the sanding out a bit more to help blend it in, and this time I wiped them thoroughly, several times with paint thinner (mineral spirits) on a rag, thinking that this would remove the dried, sanded, lacquer-dust before I applied more lacquer.
Well that didn’t work, and now I have even larger areas (where I sanded) with white specs.
What should I do? I was thinking that lacquer thinner would “melt” the lacquer dust into the finish, but I don’t want to try that until I talk to someone about it first.
Thanks for any help you can provide.
