They were grey originally but since my car is emerald green I thought I would spray them in that colour to match.
Took them carefully apart with the help of some heat from a hair dryer, then cleaned off the remains of the double sided tape and old paint(they are painted from behind) with careful use of paint thinners.
Painted the back of the growler first with silver paint and let that dry to stop any green seeping through and then gave them 4 to 5 good coats of spray paint,letting each coat dry a bit each time,cleaned up the chrome rings,stuck them back in with double sided tape and all done. Hope this is of use to other members who would like to change the colour or just refurbish their center caps.
Have Fun and Take Care
