plastic media stripping
I believe we are using a urea based plastic media, we buy it from "maxiblast I think, .
we use an acrylic media on vettes, though it seems the mid 70through 80's vettes plastic is kinda soft..........the old vettes and the new frp produced ones strip very nicely. No the parts dont have to be off, we do what we call a feather edge, we mask off all jambs , and seams where panels that are on the car meet with one layer of electric tape and two layers of duct tape.......this way the shop that sends us the car, doesnt have to do the jambs if they dont want, they just sand down the featheredge and prime, we have done it this way for almost twenty yrs and it works great, now , if a car comes dissasembled we can do a better job,a nd yes if you are l blasting the inside of the pickup box and the door and fender jambs, it'l;l take three hours or so. But this company is the best around, we do everything from the fenders and tanks of harleys still on the line..(they experimented a few yrs back with various powder coats and we stripped their boo boos, also when gm went to the plastic doors on camaros(you know , with the faired in mirrors) we stripped their prototypes while they trained their machines to paint the parts, we'd remove many layers of paint so the machines had a fresh surface.
