I’ve been painting again. This time one of the exhausts. As you can see in the comparison picture, there was quite a bit of surface rust to get rid of first. I’ve worn out at least one wire brush and a wire disc for the drill and painted about half a tin of Jenolite onto the rust to keep it at bay. The result isn’t too bad. I kept the road rash on the pipe intact, just to keep some character (and I also didn’t think filler would work on a hot exhaust).
Time to start work on the second pipe. I may see if I can get it sand blasted to save a bit of time (and wire brushes).
