Rich-
I think the new coats will be fine over the existing ones. Nitro can re-dissolve existing lacquer pretty well, I think.
I've only done 10 or so guitars with nitro, so not an 'expert opinion'...
Cheers
John

Because of the weather I have not been able to spray my guitar for 5 days. Do I need to sand it before resuming spraying? |

The nice thing about Nitro is it melts into the coats below, just make sure it is cleaned up well before the next coats. Fred |

It wouldn't hurt to scuff it a little. |

My question is, "if Behlen says to scuff sand between coats is it really ok not to sand?" I kind of figured that since nitro eats into the old finish it wasn't really necessary to sand between coats....but there it is on the can and I REALLY don't want to sand the whole thing between each coat if I don't have to. So far, I haven't wanted to risk anything and I'm scuff sanding pretty thoroughly between layers. On that same subject. I can control dust 100% in the room I built but it's not there yet since the shop is still pretty new. I expect, even though I may not sand between coats, that knocking down the big dust nubs will be important....but I wonder if the tiny stuff is something to really worry about when building coats. |

I have used Behlen and Mohawk never sanded. |
