In this video I paint all my chrome bits. Most new cars come with a heap of chrome parts like grill, mirror covers ect.
The basic process is to sand, prime and paint.

You can use a spray gun or a spray can to do the job.
If using 2k paint please do it with a good spray mask and in a well ventilated area with dust extraction.

Here is a video using the 2K clear in a can.
