80 grit seems much coarser than 80 grit. Should be 60 grit or something. There was no 240 grit, mine had 2 sets of 120 grit. I build guitars and basses and I really need to be able to sand down the bodies of the guitars that I build. The wood must be sanded to 220-240 grit to allow the abrasive compound to penetrate and lift the fibers before the top coat is applied. Now I have to order a separate set of finer grit bushings. There was no way to contact the seller with them and they are from WEN.
