Did you wipe the filler off? Sounds like you didn’t clean all the filler off before sealing. You will have to strip off the lacquer to clean off the filler. Sorry to be the bearer of bad news. It has happened to me before. Only takes once. Good luck. bob

This is what I’ve got so far. I sanded the surface after I put the wood filler on and used a tack cloth afterwards. It only appeared after the fifth or so coat of lacquer.

It looks like your tack cloth didn’t get all the dust out and it got trapped under the next layer of lacquer. Are you sanding between coats? If so it could be lacquer sanding dust trapped in the low spots. I’ve had this issue sanding between coats on walnut before.I had to use something wet like mineral spirits or water with a rag to get it out of the low spots. Just a thought.

Maybe that’s it…I did knock down a few spots on the lacquer with paper between some of the coats. I don’t think I wiped it off but it didn’t look like anything was there. Well that wont happen again. Dang! Thanks for all the help.
