If you want to paint them,you must first strip them bare.I once used a
spray paint from a can of satin black from Advance auto .Very pretty,but
they chipped whenever a key got within 20 feet of them.Didnt strip them
bare,I am told. I am now testing POR15 chassis black on them,with POR15
clear as a base. Looks same as oem.Wont chip.May sell some that are keyed
to your ignition ,some day.Try reversing the ones youhave.The left will fit
on the right,and vice vers.The underside paint is still good,in most cases.
