CHAD THERE ARE TONS OF MEDIA THAT ARE USED TO REMOVE THINGS LIKE PAINT. ONE OF WHICH IS A PLASTIC BEAD THAT CAN BE USED ON A CAR WITHOUT REMOVING CHROME OR ANYTHING YET IT TAKES THE PAINT OF. AND I'M TOLD MANY OTHER KINDS
i used bead blasting for pistons and other precise parts but for the block and intake and **** use sand but make sure you wash the **** out of the block to insure that all of the sand is out. any questions write back.
sand blasting can be a savior or damnation, the type of material you are sand blasting depends on what type of material you need. The guys at Eastwood Company , can help with the type of material you need, eastwoodcompany.com. You can us sand @ differant grits to walnut shells it just depends. All in all sand over all can be a royal pain in the end, rear end.
Just to ad something to think about, if you are doing you blasting out in the open where you cannot reclaim your material, better stick with sand because of cost. On the other hand if you have a nice cabinet that reclaims your media you don't have to worry about losing all that expensive blasting material.
I have used my sandblaster that I bought from T.I.P. for three years now with nothing but play sand bought at Lowes or Home Depot. I am blasting old heavy panels on my 63 Ford and have sprayed House of Colors Candy Red on them after sandblasting and priming them. Everything looks very nice no warping or problems like that. The sand costs two bucks a bag, and I sweep it up and re-strain it several times reusing it over and over. I do all my blasting outside on a concrete slab about 12x12, and recover about 75%-80% after sweeping each time. I have taken each panel individually, each bolt, each strap etc. apart to blast as I had rust on everything. When I worked in a body shop as a teenager years ago, the old bodyman told me that sandblasting thouroughly was the ONLY way to eradicate rust. Just my two cents!
