I have painted stainless/aluminium/zinc plated/chrome plated bodywork
on my bikes/Land Rover. This involves using phosphoric acid etch
primer. I got mine at a automotive paints shop and it was specifically
made for priming surfaces with oxide layer (stainless/aluminium/zinc/chrome).
I have only had good results with this type of primer. I have also found
out the hard way that it is vital to treat such surfaces before painting
or else the paint will flake off after a few years.

In theory, there's no difference between theory and practice, but in
practice, there is.
