Brake Drum in Gel
At first I tried just putting it on in a few thin coats, letting it turn black and then washing it off. I used that technique on both drums but I wasn't seeing much in the way of results. Then I tried a new approach on the drum in the photo above, where I applied an extra thick coating of Gel and waited for it to turn black, then scrubbed it off with water and a wire brush. This worked much better, but didn't remove all the rust in one application either. Finally, I got tricky and decided to spray the drum first with the Liquid, let it soak in, and then applied a thick coat of the Gel. This worked much better, but I still wasn't penetrating the rust fully in one application, just working away at it. Photo: Ryan King, 2006.
