I've seen similar products 'n stuff... the oil with microscopic copper/brass/iron/steel stuff that fills scratches? does it actually work? I am skeptical it does much at all, but I'm curious... they are called "Engine remetallizers." says they are only sold on ebay and suff cuz they aren't sold in america...? i dont really trust it, but heres a link... read the comments and stuff... "Quickly and cheaply repair any worn engine"
