[Vwdiesel] sand blasting - refishing mags

[mikitka]

Just be careful of the zinc Chromate dust when you do blast. That is nasty
stuff. That is if you blast stuff that is painted with that. We do at work
and have a filter recovery system that is pretty nice. The one blast tank is
a titan.  Nice setup.

I did my teardrops with glass beads, color matched to the burgundy 89 
when i had it.   They needed refinishing, as some tire shop guy hammered 
the finish off them removing them from the hub.
left a VERY nice ready to paint finish, and they are holding the finish 
well after four years.
Current owner wants to make them silver now, go figure...

I used a blastvac- a body shop spot touchup device that recaptures the 
media. Like Nick, I would recommend glas beads, as coarser media such as 
iron oxide, ground slag, etc, leave too rough a finish for painting.
There was NO surface prep required other than a wipe with cleaner after 
glass beads.

Size of machine?
all depends on how patient you are Evan.  Bigger compressor is better, 
you can add just a tank for more reserve air, to reduce the time spent 
waiting for the compressor to recover.  Cabinet needs to be big enough 
to physically fit a rim, and the gun.  I have all the stuff to blast 
continuously, but if you have more time, you can wait a bit for the 
compressor...  cabinets recover the media, so you reuse it until it 
wears out (and glass wears out fast), but plan on using a cheap canadian 
tire shop vac with a drywall bag in it to suck the dust out of the cabinet.
