Can you not get a local Bodyshop to mix up BMW Paint Code A80 and put it in some aerosols for you?
There are lots of people asking the same question in the intrawebs but there doesn't seem to be a direct equivalent so far that anyone has found.
These folks will make up the paint, but you need the spray kit. I know some spray shops will mix it into aerosol sprays for you but that is the limit of my knowledge as I have never asked one to do it for me. Sorry..
