I used to swear by the alclad chrome, they do this in aerosol and jar. But I have just used some Spaz-Stix chrome, and it kicks ass.
This is also available in chrome and jar, but there are limited places sell it. I get mine from the land of the rising sun.
I found the Fastrax stuff ok, but it left the finish a bit 'patchy', some places were nice shiny chrome and other places were just like a smooth silver.
Faskolor do a 'glitter chrome' but its NAFF!! with a big fat N.
