Since the rust is kind of minimal I am going the simple route with POR15 or Some similar thing. I don't know diddly about welding but my son is a welder by trade so I'm going to try and cut out and weld in new bottoms to the wheelwells. BUT, my kid is really a structural welder, he builds stage sets and other things more in the construction business. I'm sure he knows how to do what I need but I'm wondering, are there already stamped out pieces for this kind of repair available? This is the only area of the car with any rust showing and I'm going to treat the rest of the underside to a wax and oil mixture I read about here (Waxoyl ??) If I do decide to paint the beast I'll be fixing some minor surface rust too, but hopefully I'll be able to at least protect the car enough to get me through the next few years. Lots of good suggestions here. Hope to have a much better looking 300D by mid-summer. Thanks.
