P&S Sales developed a line of professional car care products under the name of the Double Black Collection, a private label for Master detail trainer Renny Doyle. This cutting edge, premium brand is approved by Doyle as the best standalone products he has found. Many of them are used on prestigious detailing events like McCall’s Motorworks Revival, The Quail at Monterey Car Week, and the preservation of the original Air Force One presidential jet at Seattle's Museum of Flight. But, they have also added new products, built and honed to Renny’s specifications for consumer use. In every case, each product performs to the highest standards of today's technology.
