You see vapor blasting associated with motorcycle resto shops for some reason.....
Results are amazing - vapor blasting on brass and copper is WOW!
I used it a lot on the ferrari restoration - uses ultra fine media, chemical agent and water under pressure. We did alt cases, trans cases and believe this is the ticket. Tumbling works well also, but you get the media marks in the metal which gives that unique sheen. Remember that on 4 sp cases, it seems that all the alum seem to be of different grade, thus the finish on each is a little different.
