A wheel re-finisher recommended by the local F dealer has refused to do my wheels stating they are cast magnesium and will burst into flames during their process, apparently powder coating. I explained that even if they are magnesium they would need to be nigh on 900*f to ignite. Mine have some paint peeling, the metal beneath doesn't look like magnesium which I'd expect to be very dark if exposed. And they seem way too heavy. Does anyone know what the alloy really is? Also, still looking for correct paint color as it seems I'll be doing this myself.
