I read in the description that this limited version of car shampoo has a formula change from the original. I regularly use the car shampoo for my business, so the comparison was easy to make as far as differences between the standard and limited formulas. Right off the bat I could tell the anniversary edition was thicker. So I put some of the new anniversary juice in the foam cannon and began the wash process, with the other major difference I noticed being the clinging capability. I was able to produce a rather thick layer of cherry scented suds on the paint, even with a layer of paint sealant and Americana wax on it only a month. I would compare it to the ultra shampoo but not exactly the same. Maybe even better. I would love to see this formula stick around.
