gedlee Posted May 20, 2007 Report Share Posted May 20, 2007 I'm trying to repaint a bass using plain white dupli-color paint,sanded,primed ect.. painted the base coat and tryed to sand it with 600 wet before the clear coat and the paint started to turn a yellow color? Has this happend to anyone else with white or any other color? Am I doing something wrong? Its been a real pain in the a.. Thanks Quote Link to comment Share on other sites More sharing options...
Southpa Posted May 20, 2007 Report Share Posted May 20, 2007 You're shooting lacquer. Its not really necessary to do any wetsanding between color coat and clearcoat, unless you've really got some nasty runs everywhere, and even after that more color should be laid down. No mechanical bond is required between coats of lacquer. The solvent (acetone) in the new lacquer coat will fuse with previously laid coats. So shoot your white as best you can with rattlecans, cut away drips, runs etc. with a razor when dry then shoot the clearcoat. Wetsand the clearcoat.

Yeah,I didn't really plan on sanding it(The base coat) but I got some lint or something on there and tryed to sand it out. Any ideas for that situation?

TonyFlyingSquirrel Posted May 24, 2007 Report Share Posted May 24, 2007 I used their Sandable Black Primer for my RG7620 re-finish, very nice, easy to sand, takes a few coats to fill the grain, but I didn't start out with heavy coats either. I sanded the body down to 800 grit, then primed. Quote Link to comment Share on other sites More sharing options...
Maiden69 Posted May 24, 2007 Report Share Posted May 24, 2007 The white shouldn't turn yellow because of sanding. Maybe there was something in the water or the paper you used? Anyway, you can continue to put coats and sand with 600 until you think that the coat is nice and smooth, at that pint just shoot one more nice white coat and clear over that without sanding.
