my frame was done by a buddy of mine that works for an aircraft company that has the military contract to do all of the hardcoating on their hand guns and gun barrels on the helicoptors. so it's not actually anodizing it's called hardcoating. the company that did it for me said this coating structurally
make the part stonger. the finish looks unbelievable
in person.
that sounds similar to the coating on the moto axles from Black widow.
