Is too-frequent use of DRI WASH GUARD harmful to the paint?
No. DRI WASH ‘n GUARD can be applied daily without harming the painted surface. The product works only as hard as necessary. On paint in excellent condition, it cleans as gently as water. On oxidized paint, DRI WASH ‘n GUARD cuts through layers of oxidation each time it is used. The more DRI WASH ‘n GUARD with exclusive formula PolyGuard-3 is used, the more brilliant and smooth the surface becomes, and even more resistant to the elements.
