Awesome tire shiners are very effective . They use a 8" x 104" lg rotating brush. The design is very simple to work on.
Awesome is the only type that has a patent on a lower catch pan. This allows the tire shiner dressing to be replenshed on the brush, thus their machine can use as little as 1.5 oz of product. Istobal manufactures the unit for in bay automatics and Performance wash systems manufactures the tunnel unit. Both companies manufacture under royality from Awesome fabricating in Bowling green.
