Optimum Car Wash is currently my favorite shampoo and I use it on every vehicle I wash. So far, it`s been used on CQuartz, McKee`s 37, and Gyeon CanCoat coatings with great results. I`ve also used it on Collinite 845.
In every instance there was no change in the properties of the LSP. To me that`s a good indication of the shampoo rinsing away and not leaving anything behind. Optimum really combines the best properties of several shampoo`s I`ve tried into one product.
