sorry I'm not in that area but here in North Florida, we don't have ANY boutique type shops. At least none that carry what I would like them too..LOL.
I've learned to fish out auto paint, autobody shops, marine/boating stores, etc to find some hidden gems such as pads, polishes, sealants etc. It's still not a one stop shop type of thing but in a pinch I know where to get what I need.
