My father is a sandblaster and painter. We know how to do it. You can warp the hell outta body panels super easy,
esp w big equipment like padres got. Fine sand and black beauty don't tear it up as bad. General rule is don't blast
exterior panels period. I'm talkin structural/floor/panel hidden areas.
Can use corn cob or walnut shells as well if non-abrasive is required. Soda blasting is a
friggin mess. Too fine any humidity screws u up. Shits nasty PITA in my opinion.

I'm trying to bribe this bloke from Newton Abbott, United Kingdom rite now to expedite a box to me, I'm up to
£240 shipped, that's my ceiling I think.....
