I finally figured out the best way to remove the finish from a black aluminum hub. I had tried everything from aviation stripper,paint remover and could not get any finish off then tried something new. I found out is not powder coat it, is anadized. the best remover is easy off oven cleaner it instantly removes the finish be very careful and rinse the hub every few minutes with clean water and re-
apply, also use a green scoring pad and wear gloves. I hope this helps the guys who want a bright finish.
