i also had a tough wayne 60 base to blast. it started out blasting nice fast & clean. BUT then all of a sudden it wasnt cutting anything off then i remembered that the last time i blasted something i ran out of *Black Diamond* blast sand (coal) & there was silica sand in the bottom of the blaster. it wouldnt cut that cast iron clean for nothing!!! -------- sometimes i smooth out the bases, sometimes i leave the cast iron look. i like that cast look with a super shine on it! LOOKS OLD, LOOKS REAL! but if its pitted bad youve got to smooth it out!
