Hmm, you seem to be a little 'abrasive' yourself.

I have had numerous pieces for my motorcycles chromed and it is true the shops recommend a non-abrasive chrome polish to shine the piece. However, if you are dealing with old rusty chrome and the aim is to get it back looking reasonable then they recommend fine brass wool followed by hand applied very fine abrasive polish.

You can yell "never use steel wool" but not offering any alternative is not very constructive. Incidentally a 5 micrometer chroming job is a little thin, most places seem to claim double that for a high quality cosmetic plating.

On another note that is indeed a sweet bike.
