If you want to drive to Martinez I have heard A-plus does a good job , or if you want to head to sacramento I know there are alot of people that have had good results with the detailer at Acme Tops and Tunes.
Richard's Boat Detail is in Discovery Bay. He can do your boat on your lift, in your driveway, or bring it over to the house on Willow Lake Rd. 925-784-4924.
