I'd opt for paint stripper and bronze wool, but if you use the "safer" strippers (and I do) and you leave them on for a spell (which they recommend) you may find the water-based formulas start to cause surface rusting if the chrome isn't perfectly sound. But a little rust can be polished off and I'd warn you off the old 'unsafe' strippers: tho they work faster they are much more dangerous to your skin and brain cells...they'll even eat thru heavy rubber gloves. Remove the headbadge so you don't accidently damage it and kiss the old decals goodbye. Once done it should look stunning!
