[spareparts]

i use the Porter Cable 6" da ( the one that looks like a grinder) on everything, I have put this thing through hell and back and it keeps going (probably will break the next time I use it), i just usedit with 40 grit to sand all the old gel off the glastron, used it with 1500 grit to finish out some gel before I buffed it, it works great. I've even used it to prep gasket surfaces. I highly recomend it
