Decals come off dolans easy enough. They are stickers not paint, but under the lacquer. You can take them off neatly with some heat, a sharp object and patience. If the frame is matte black you won't notice the difference. If it's gloss black then in light it shows. But frames that are not black will get dirty quickly where the decals were. The dirt can be fully cleaned off but you'll need to use a solvent and do a proper job. Remove the decals and cover with sello tape or just keep them and cover over with electrical tape.
