I've already had my Model S given the Opticoat Pro treatment by Joe Torbati at Orinda Auto Detail, so I don't need expertise that advanced. But Orinda is too far for the routine car washing, so I'm looking for some place fairly close to Oakland that will use proper methodology during a wash as not to damage the finish; e.g., a three-bucket hand-wash system. (It's impossible to tell this from Yelp reviews because the reviewers don't demonstrate that they would know right from wrong in this regard, and I visited a highly favorably reviewed place and they were not using even a two-bucket system.) Any East Bay recommendations from the Bay side of the hills, e.g., Oakland, Berkeley, Alameda, or Emeryville? Thanks in advance!
