I recently picked up 3 pinball machines (X's and O's, Whirlwind, and Freddy) for a song, but they had been stored in a damp area and had some rust on them. Working on cleaning them up, and am not sure what to do about rust on parts like the side rails, legs, etc that are too big to fit into a tumbler.
My original plan was to sandblast the legs and and side-rails, however most people seem to be recommending chemical dips. Is one preferable over the other? I could sand-blast, bead blast, or just go with the dip. If I go with the dip, is http://www.harborfreight.com/1-gallon-evapo-rust-rust-remover-96431.html a good option?
Thanks!
