| The shampoo is just like the Meguiars Next generation shampoo, its got special polymers in the shampoo that make the water sheet off. The problem with my washing is the amount of chalk in my water that stains my car if it drys on it. The filtered water will work perfectly with my Meguiars shampoo. I really want one! Not going to bother at all with the refills of the shampoo. I'll use my good meguiars stuff! |
