I posted a thread on another forum on how I did a quick and easy re-paint of my Camry alloys, and received an interesting reply from a member who cautioned against sandblasting alloys because it would cause structural damage:

"What happens is the molecular structure of the alloy gets weakened from the sandblasting and can lead to catastrophic wheel failure. It can't be visually detected, but under a very high power electron microscope - the damage is evident in the metal, and the strength becomes compromised beyond the surface."

Since I was planning to do the same refinishing on my '86 560SL wheels, I was wondering if anyone here had heard of this before, or would care to venture an opinion? Here's a link to my thread http://www.toyotanation.com/forum/showthread.php?t=293160
