Re: Blasting media
Blasting does NOT CREATE HEAT!!!!!!!!!!!!!
It is the equivalent of beating the tar out of it with a ball peen hammer, stretching the surface, that causes warping. Therefore, lower the air pressure and blast at an angle to strip off paint coatings.
Pot blasting is too messy and a pain in the rear to do at home. Money well spent to drop off my parts at a professional blaster. Only time I use the pot blaster at home is when I have something small that needs to be blasted before welding in a patch panel. Sometimes it is not practical to haul something to the blaster that would only take 2 minutes.
Black beauty is only good for about 2-3 cycles, and is cheap. The blaster I take my stuff to uses aluminum oxide. However, don't let them do it on a flat surface like a roof, door or quarter panel. That gets done with 80 grit D/A sander.
I use black beauty in the pot blaster, and aluminum oxide in the blast cabinet.
