For years these quarter panel has driven me nuts. I knew there were mounds of rust someone had fixed with bondo and that the putty had broken down

I went to yard and cut a replacement. I have a DEWALT 18VDC Sawzall and sometimes I think it could cut through a panzer tank!

TONIGHT I got all excited by this Forum and decided to fix it once and for all

I cut it open and I guess I was right, it was 99.9 % rotted steel
