UPP, UPPS, PwS and a lot of other sealants get slicker and look better after they had time to bond to the vehicle. I guess the chemicals need some time to bond in order to get the best looks, slickness & protection. I'm guessing that's why it's a good idea not to drive a vehicle you applied a sealant on within 2-3 days (if you looking for maximum durability).
I have a Mazda 3 that I use this stuff on after every wash between waxing every month.
I do have to admit it does seem like the gloss gets more intense a little after the application of CM. But it could be in my head. Either way I'm happy with the spray when compaired to what I used to use a year ago, Turtle wax express shine stuff.
