I would just buy a can or two of good paint stripper and give that a
try.I own three sand blasters,one of them I built using a big steel tank
I bought at a junk yard,and the other one is a dinky little sand blaster
I bought for about twelve dollars at a Wal Mart store and the other one
is a little spot blaster/sand blaster I bought from Eastwood Company.
