Chroming wheels in L.A.?

[Noah930]

Any recommendations for wheel chroming services in the L.A. area? Not for any P-car, but for a Lexus owned by my parents. They seem to have a very slow leak that doesn't seem to be related to tires or valvestems. So they think it may be the result of a couple curb rash dings, or they've been told by a tire guy that this can happen with chrome flaking off or rust underneath the chrome (along the bead).

So, any recs for shops/services in the L.A. area?

Grade A electroless bright nickel plating. Mil-C-26074, class 3.

It's like a rich looking dull chrome finish. Look in the yellow pagers for a plating shop.
