Sand it very slowly with a silica based sand paper. Using a grinder/polisher could cause it to ignite with certain types and high speeds. The autoignition temp is only in the 800 degree range and a spark can set it off.think they would look good black, iknow magnesium is highly flammable but i think u have to actually light it to get a good fire. just to be safe wear a mask for the dust
Use fine grit and wetsand, then paint when you're done.yeah i'm pretty sure they are...
i just don't know if i want to sand them down or not...that's not really something you can come back from.
once you sand up the wheels they are pretty messed up...
i don't know, hopefully i can find some decent rims / tires for pretty cheap.
