Here’s a quick breakdown of the repairs to my spare fender. I started with an order to SendCutSend for a set of new laser-cut steel donuts for the outside and inside edges, as well as three 1/2″ strips to bend for a flange to connect both. I welded the outer flange in first because it had a slight curve, then built an inside section and tacked that in place. When I saw that it would collect rain the way I’d built it, I used a second donut and strip to mount flush to the outside edge and tacked it all in place. Next was welding a small patch in at the bottom, where water and mud pool and rust the metal out from the inside.
While that was cooling I sanded the top layer of blue paint off the fender to reveal some past damage and Bondo, which was not unexpected. I skimmed some Bondo over the two welds and sanded everything down, but the fuel mount area is going to need a lot more attention. I’m looking around for alternatives to off-the-shelf Bondo and have found that Evercoat products seem to get good reviews, so I think I’ll buy a gallon of that in the springtime to continue bodywork projects.
