After a nice cup of hot coffee, and giving the fender time to dry off, I worked out any dings, and filled the 5 holes. It is amazing much thinner the inner fenders are than the rear wheel tubs. I had to lower the speed of the wire on the welder...it would have blown holes though this sheetmetal without any effort.

Next, I removed all of the paint/primer so I could remove any surface rust hiding below. After it was nice, clean, and shiny, I shot it with metal etching primer and skimmed any slight imperfections with a thin layer of filler. I will sand most of it off tomorrow after it is cured completely.
