sorry, i meant "If I" have a compressor already (my typo) what else would ya need ?

hose and a bucket of blasting sand basically. depends how fancy you want to get, like i said above i have striped a car with a $20 blaster gun from supercheap, lol was slow going but worked great, which virtually was a blaster gun, a bucket of sand and a hose going into it with a filter, and off we went, you can get reall fancy and buy all that other stuff like reg tanks and fancy filters and what not if you are going to do it serious but odd jobs you dont need much really. lol and you could always get the other bits if need be, its pretty easy to dodgy up a blaster setup to get you going,
