I've got some rust breakout around the outside edges of my rear wheel wells of my 85 300D. Part of me says try to get it welded, and the other part says just use the Best Putty you can find to repair it. I eventually hope to restore this car to NEW or near new, but cost is a consideration.

PRO's/CONs Welding: I have heard that welding on Mercedes 85 300D is not so good because of high lead content of stelel and in the end you need Putty anyway to finish it...

PRO's/CONs Putty: Putty always breaks out in 5 years, which is how long I have had this car.
