I think the only safe way is to use paint stripper or to sand. Sandblasting can warp panels as everyone will be [and has been] lightning fast to point out and will remove some thickness from your panels, and to begin with, 1200s are not made from the thickest of sheetmetals.

Dipping removes factory rust proofing from places that are hard to re-rustproof completely, especially inside your chassis rails/subframe and inside the cowl, and even if you do rustproof these areas there may be some acid residue that will render your efforts useless.
It's one of those occasions where it's better to do things the harder way... [I think]
