i am going to rechrome some parts on my commando starting with the foot pegs. i have dipped them in hydrocloric acid to remove the old chrome and underneath the old chrome is something norton used to fill pits and flaws in casting. can anyone tell me what that is? reading about chrome online some people have used silver solder to fill flaws. my natuaral inclination would have been to use brass to fill any imperfections, but don't want to use anything incompatible with what is already there. thanks in advance for any information.
