well the latest is, my hands are killing me ive been scraping on this rear frame for at least 40 hours so far.that factory undercoating is sticky as *****. so im using a sharpe cheisel to get that off and getting the inside of brackets along the upper frame real bit*h . wire wheel works on rust only and cant get in the nooks and crannys.i think im going to use por 15 silver because of the metal fillers in it.let me know if you guys ran into any trouble with the silver por15 .the frame had pitting . ill let you know how its going if i can type after i get done. later
