so yesterday i took on a detail on a black SUV for an interior shampoo and exterior wash/wax. little did i know that it was going to be damn near 90* outside. lets just say that my traditional wash method was leaving more spots than a dalmation. thank god i had ordered up some ONR and received it a few days prior. i used scotts method and BAMM! no more spots. i think its safe to say that i have a new friend when it comes to washing in the heat.
