Hi Scott,
Stick to the blast cabinet as suggested but used glass bead as this is easily filtered and re-used. Most git types break down. NEVER
use sand due to the health risks associated with silicosis( I think that's how it's spelt
). Much of the small stuff is very tedious and open type blasting will waste enormous amounts of grit for what you want to achieve.
Use a blasting company for the larger bits - chassis, diff housings, rims etc. as these pieces usually only number a few in any resto.If you are in the Sydney area there are plenty of places which do the big stuff. I'm in western Sydney if you need some of the larger stuff done and I only charge club prices for anyone in a MV club.
Hope this helps
.
Regards,
Brett.
