I tried to find my old posts (threads on this)...sorry for yet another thread on this subject. I have the top of my repair guitar fully sanded to wood, dings filled in with lacquer and 2-3 sanding coats applied. Its time for the finish layers. The question is how many, and do I have to sand between (actually, should I sand) between layers. Once final layer is down, I planned to start with 400 grit, then 600, then move on to micro-mesh. I have some of that auto polish/compound stuff I have heard about in here. I was planning on using a polishing arbor with that. Anybody want to correct/modify the recipe? Help is appreciated.

Mike

I shoot 4-6 coats...each about an hour apart. Then let it cure for two weeks. Level sand to about 400 grit and shoot 4-6 more coats. Let cure for two weeks and then wet sand as youy described. It really helps to let the lacquer cure out sufficirntly before sanding.

JJ, why do you cure between the coats for so long? Every recipe I have seen or tried only cured the lacquer before the wet sand /buff operation. I would think you could spray 4-6 coats of lacquer, wait overnoght or a day or so, and then level sand with 400. Then spray 4-6 more coats and sit for 2 weeks then wetsand and buff.

I only wait an hour between coats. I wait 2 weeks while it cures before sanding. There are 2 sanding sessions...one for leveling before applying the next 4-6 coats and the final wet sand & buff.

My experience is that it sands much more efficiently the longer it cures. It will shine up to a greater sheen the longer you wait for final sanding. Hard, cured lacquer sands much better than partially cured (softer) lacquer. It takes patience but I believe it's worth the wait.

Thanks! Great recipe JJ.

For the final buff (after wet sand/micro mesh) can someone suggest a polish recipe?
