well my old man's purchased a new media blaster/grit blaster basically if you dont know what they are it strips metal/alloy back to its bare material.
i have a good contact for powercoating and i have use of metal buffer ideal for polished lips etc on rims.
also the media blaster is ideal for subframe re-builds etc, just takes the work out of using sander/sand paper.
hit me up if your interested in anything and i will get you a price.
its not a free service but being my dads equipment and mates power coating as long as it covers costs you just owe me a pat on the back and a beer wouldnt hurt (i like corona) lol
i will post pictures of my BBS RC 041/042 staggered set up i am doing at the moment when they are finished.
cheers
