Can anyone recommend a paint shop in Los Angeles area that will paint my chrome bumpers to match my factory paint?

 

Any Maaco, One Day, Car Coa, etc can match the paint. It's the painting over chrome that is the hard part. The trouble is making the paint stick. I would imagine getting them sand blasted first might do the trick. Simply scuffing them with sandpaper, iether by hand or with an orbital or DA sander is not going to be enough to get the paint to stick for a long time.
