Once you get below the "fluff" = you will find that it's as bright, if not brighter than you need. The = only hammers that I would consider adding chemicals to are Steinway = hammers, or else hammers where some block-head has killed them by = over-needling. By the way, when I sand hammers, I don't use a paddle. I use thin strips = which I have cut to be just wider than the hammers. It works out easier = that way. My last pass is with 800 grit, with the hammers blocked up to = the let-off position and leveled. You have to blow the hammers out when = you're done, but when do you not have to do that?
