So. Baking it off. What degree roughly ? Will that damage the billet where they wont polish up good ?

i burned powder coat off with a propane torch.  took an hour or so to do a whole frame, but worked good.  i bead blasted it afterwards to get a good, even finish on everything.  

 

i bought one of the cheapo ones from HF: http://www.harborfreight.com/propane-torch-91033.html

if you torch off powder off alluminum its very easy to get it to hot and melt the alluminum. torch works great on steel parts like a-arms, frames swingarms etc..

 

at paint stores you can get gallon sizes or more of paint thinner or paint stripper.  drop them in the bucket and let them sit  it will take it all off..   OR  if you have a powedercoated local you can ask them if they have a strip tank and see if they will strip it for you.  

 

or you can bead blast it all back off  might take a long time.

He's right..

 

Over time, aluminum forms a thin coat of aluminum oxide on its exterior, which melts at a much higher temperature than aluminum. So, before welding any piece of aluminum (even a brand new piece), you have to clean away the aluminum oxide.

I misunderstood. I thought he was saying a different powder was used on aluminum than on other metals.
