i wouldn't use the scratch-remover on the decals or chrome or nickel parts. i'd be afraid it would damage the metal. on those i bought Simichrome polish at my local hardware store. it shines them up beautifully and won't hurt anything.
one little trick that i picked up somewhere here was to use cotton string, just an ordinary white soft string, to help polish the round parts. cut a long piece, and double or quadruple it up so it's wider and put a dab of the polish on it. then wrap it around parts like the needle shaft, criss-crossing over the front and see-saw the string back and forth. as it gets black, move to a new section of string and another dab of polish. that worked great for me. i also used old t-shirts for polishing rags.
