Default Re: Brake drums

While I don't use Randy's drums, the process should be the same. We wipe down the outside of the drum & hub with wax& grease remover, then mediablast the exterior to crate a slight texture. We then spray a thin coat of catalyzed epoxy, and as soon as that has flashed we come overtop of the epoxy with one coat of gloss 2k urethane paint. Years later, the drums still look fresh and no blistering. Personally, we don't care about the interior, but that could be painted too. We install races after painting and cleanup, and any overspray on the lining surface gets removed during the machining process to true the drum to the hub.
