Apply a bit of "cleaner wax" to an original painted area. If the polishing cloth you are using picks up the color of the paint then it is single stage.

Not necessarily a 100% test since if the clear coat has completely worn off the base coat will come off but it's a good 90% of the time test.


Color code 040 is black single stage in the original paint. Doesn't mean the car hasn't been re-sprayed somewhere in the past with a clear coat added.
