Today I went to a junk yard somewhere out in the boonies to pick up a pair of fenders for my W114. They came of a 220D and I was told that they were rust free and in good shape. Well... they had rust on the edges and someone scraped it which what looks like a fork lift truck fork but I think I could work with them so I negotiated them down to $40 / fender.
When I got home, I tinkered a little more with the 300D by sanding down the roof and the rust spots to bare metal, then applying spot etch primer over the metal parts followed by bondo so that I have a smooth surface. Bondo is not a good product.
Lots and lots of sanding was then performed with lots and lots of sanding to go.
I did end up wet sanding and buffing the trunk lid very quickly before it got dark. I think I did a pretty decent job on painting but my prep work was not that good. I'll pay more attention on the rest of the car.
