Aluminum Oxide? Good thing or Bad thing?

I was going to use glass beads, but was kind of curious about this.

Bad thing for body panels it will create too much heat and warp the panels. Alum Oxide and glass beads are best for heavier parts such as brackets and suspension items.
Use plastic media or walnut shells for body panels.
When the Mach I was painted they used walnut shells to strip the car and the result was well worth it

Aluminum oxide is very aggressive and very expensive. When the smithsonian works
on priceless old airplanes they blast with walnut shells. They take off one layer
of paint at a time. They also have a bottomless pit full of time and money. You can
really mess up body panels with blast media. use a chemical stripper and elbow
action. my advice.

I know they can warp panels but I've heard people use it. I guess it all depends on how it's applied. I've even heard of people sandblasting panels too, and I thought that was a no-no. I'd go ahead and use what the previous poster said about walnut shells just to be safe. I'd sure like to know more about this tipic though. Maybe, someone else can chime in...

I posted about this on the old VMF and a friend of mine told me that my car is gonna be "sugar blasted". I know its not actual sugar but somebody on the VMF told me that this meant that they use some kind of soda or something. The friend of mine is trustworthy and tells me it is really good to use but kind of expensive.

I read in an old issue of Truckin' magazine that a company was using baking soda to strip the paint off of sheetmetal pieces. They demonstrated the procedure on a Pepsi can which revealed no warpage to the can after completely stripping it and that's pretty thin stuff. Scott
