Doing some clean up work, the Sportster has been on the road for a while now so it was time to check for rust and clear anything up
Little bit inside the shock tower area, most was on the metal upright towards the back of the car.

The good news is that it was all surface, no structural issue. The worst part was the end of square bar under the back runs along the tank.
Cleaned everything up with a wire brush on the angle grinder, treated with loctite rust remedy and painted with chassis and rollbar paint. Also to go on later some underseal with waxoil.
