i strip with deluted phosporic acid, and wrinse,
then beadblast with aluminum oxide 100 Grt,
for fine, i use ultra fine glass beads, 400 grt i do belive..been a while since i ordered any.
anyplace that sells beadblast cabnits should carry media,
turn your air pressure down to 60 to 80 pounds, and keep the gun at least 6 inches away from your work.
and only put clean gunparts in that cabnit,
no car parts, bike parts ect..only gun parts.
change your media every 6 mos. more if you use it daily.
