best way to refurb 2 dial dash cluster

[flyingbanana]

ive stripped my dials to try to find a electrical problem, but while im their i thought ill refurb the dial cluster

 

but looking at it the silver/chrome ridge that goes around the clock it appears not to unclip from the rest of the unit

 

i wanted to repaint the unit but some how keep the silver ......any ideas how to do this or any one have pictures of a refurbed dial cluster to give me ideas how to do it

 

thanks in advance

you could always mask the chrome edge and trim with a blade but it may pull it off when you remove it worth a bash
