I have a black '03 S-works hardtail that I would like to remove the lettering from the down tube and toptube from. The letters have started to flake and I want to just remove them. I've seen a couple of frames like mine with the lettering removed so I know it can be done. I've tried paint remover and rubbing compound with a polishing wheel. Neither worked. Has anyone done this and if so how did you do it. Thanks
