The real way to chrome is - Copper first (this is for several reasons but one is against corrosion) - then Nickel (that's the shiny bit) then chrome which is a hard anti abrasive cover.
A modern alternative to lead is oddly ACF50. Apply and rub into the chrome well - then leave it a GOOD 3 months to fully penetrate and dry a bit.
That's pretty much the standard in the US, which is what is meant when chrome shops, or suppliers, advertise "triple plating". Conversely, I'm told that much of the imported chrome, primarily Chinese, is not.
The owner of a local chrome plating shop gave me a tour of the facility a few years ago and showed me the process. I couldn't wait to get out of it though because it had all the trappings of a toxic waste dump. The owner died riddled with cancer at about age 50 and I was not surprised.
When I sold my three HDs over the past 5 years, a 1978 FLH, 1988 Electra Glide Classic, and a 2001 Dyna, the chrome still looked good on all of them. The chrome on my 09 R3T seems to be holding up well but I keep it in a temperature & humidity controlled shop and regularly wax the chrome bits.
