Did you call any paint suppliers anywhere in LA?
Glasurit is now a brand of BASF. Go here:
http://www.basfrefinish.com/ and you should be able to find some on-line retailers.
Alternatively, there is contact information there, and you can call and ask.
Lastly, just look up "Automotive Paint Supply" in the Los Angeles yellow pages, or similar. Find the one that sells BASF.
