The Mini Speedy Surface Prep Towel is essentially a microfiber towel with a high-tech polymerized rubber coating applied to one side. Also known as a Clay Towel. This polymerized rubber coating grabs above surface contaminants and pulls them away from the surface, leaving you with contaminant-free paint.Shiny paint comes from clean paint. A traditional detailing clay bar will yield 10-20 uses, depending on how contaminated the surface is. The Speedy Surface Prep towel will provide up to 100 applications, making it far more cost effective in the long run when compared to traditional detailing clay bars. If you drop a clay bar, you are forced to throw it away. With the Speedy Prep, simply rinse it off with water and it’s ready to go again. Use a quality lubricant like Wipe & Shine, lightly wipe down the paint, glass and chrome and follow up with a microfiber. This leaves the surface ready for compound, polish or wax. For stubborn stains like bug splatter or tree sap, use with formula #109 Kleen all. Smaller 7" x 7" size is still big enough to to take care of most jobs.
