Thanks for all the input. I may very well end up going the Colorrite route but I'll hunt around a little more. All I'm looking to do is paint the chrome knob I'm using for my saddlebag key to make it less conspicuous.

I get the 'time vs money' argument - but I'm in no real rush so not having to invest dedicated time to the search - and 'going to look for paint' is a great excuse to go for a ride.

So far Home Depot & Lowes are a bust. I'll try a couple of local auto parts stores next. If I do find something I post it here.
