Mayaman,

I bought it at Auto Zone. The brand is StyleGuard stock # T3605C CHROME. 3/8" x 18' WHEEL MOLDING ROUND CHROME.

It isn't really round, it just has a rounded surface with a peel and stick adhesive on the back.

The factory silver trim actually has a larger surface, so the chrome replacement creates a slightly finer line. Looks much better than stock.
