Gee, maybe I'm burying my head in the sand, but I'm not worried about powder coating aluminum.  I've had my control pushrods (6061, and presumably buckling-limited rather than ultimate tensile stress limited) and my landing gear (anyone know what alloy?  I don't.) powder coated, though I didn't allow them to sandblast them first.

I haven't seen legions of powder coated aluminum bicyles cracked and broken in the gutters of America, so my instinct says it's not a problem.  However, I confess to very little direct knowledge of the issues so I'll be pleased to hear what the more informed list members have to say.

Still, if powder coating destroys aluminum, why does everyone do it?
