Hello All, Seeing Dale's B board prompted me to get your take on a finishing schedule for lacquer on soundboards (Sitka, if it matters). Currently finishing a M&H BB board, which has not yet been installed on rim. Thus far: Board has been sanded to 220 grit, sealed and colored with shellac flakes and lacquer thinner (tawny - amber look), raised grain scrubbed with pads, two wet coats of high solids lacquer sanding sealer wet-sanded out, one heavy wet coat of high solids semi-gloss lacquer (amber) wet sanded to 400 grit and steel-wooled to even out. Will go higher on the grits and wet work depending on suggestions. In the old days I used to use abrasive powders such as pumice followed by rottenstone. Are these now out of vogue? Now, it looks pretty darn good as a sort of satin-sheeny thing, but what else do some of you suggest? The final appearance I am looking for is somewhat glossier than it is now, but not necessarily high sheen. What about paste polishing in the final step? Use of electric polishers? Etc. Thanks!
