This http://www.vitrogrit.com/ is ok to use outside of a cabinet meaning blowing into the air?

[clance54]

Anyone know what media is safe to use outside?

[Matt@Eastwood]

Sand would be just fine, it obviously is going to get "everywhere", but won't hurt mother nature. Also depends on what you are blasting first, as to what media to use. Another trick is to build a temp. blasting booth outside where you are working (I've used just plastic or tarps set up). This makes for easy clean up of the media.

Yes a medium grit would be just fine, although I would suggest completely disassembling them before blasting. The media will get "everywhere" and could find its way into the boots covering the piston. I've found doing this before rebuilding calipers to be the best bet.

I have tried sand and the vitrogrit and the vitrogrit works much better.80 grit is about right for most automotive apps You will need to use protective gear when blasting as breathing blasting media and rust or paint chips is not a good thing for the lungs and it is a good idea to keep pets, small children, and others that you may like out of the blasting area. Read up on silicosis and other lung issues before you decide to do this..and try to keep the blast media contained somehow..

The use of sand as a blasting medium is controversial in hotrodding.

Is Glass not a better option than sand or is it not powerful enough to strip body panels ?

Starblast has only trace amounts of silica. Vitrogrit is crushed glass. According to
http://wiki.answers.com/Q/What_is_glass_made_of common container type glass, the main source of scrap glass, is 74% silicon dioxide (silica) by weight. Can't draw any conclusions as to how it might work, but it would appear to be every bit as unhealthy as sand for blasting use.
