I wouldn't use a Fitz-A-Dent on bicycle tubing. The tubing is pretty thin, and the spot welding process may alter the temper of thin, higher-quality tubing (531 or Columbus).
I've rolled the dents with aluminum frame blocks on a couple frames now, with mostly satisfactory results. The dent won't go away completely, but with a little JB weld as filler carefully feathered, it disappears under powdercoat.
