Cquartz perl

i am currently using it on the wifes bmw and im very impressed, its dry to the touch after about 30mins and leaves a nice finish, use it neat on tires or for less gloss do a 1:1 dilution for easier application and less gloss but imo neat is best for this product on tires and bumpers. also great for dressing engine bays.
