if you're seeing the chrome as "yellowish" you might actually be seeing nickel, which has a warmer and yellower tone than chrome. Typical "3-stage" chrome plating consists of nickel plating underneath the chrome (nickel is stage 2, after copper) if so the plater might have laid the chromium on extra thin in spots, not the sign of a job well done, IMO.
Chrome has to be roughened (needs to have some "tooth") for most paint to stick well...I'd talk to an auto painter and ask him what paint he thinks has the best "stick" to chrome, but if you're just looking to add paint in lug windows: One Shot Signpainter's enamel is my fave.
