There are some parts where a wire wheel just wont even help the rust is so bad. Next year i'm going to buy a new frame and replace this old rusty one, but until then I would like to at least slow the rusting. I've heard of another product called Chassis Saver, which is supposed to compare to por15...do you know anything about it?
