Probably have to rent one for the day. Can't be that expensive. Try and think of anything else that you need sandblasted. car parts, anything laying around the joint thats rusty. If you rent then get your money's worth. Oh, and you don't need any kind of special expensive abrasive either. Play sand works great. If you know anyone that has a glass beading cabinet then thats even better. (Leaves a smoother surface then sandblasting does)
