I've been using upp and love it. I'ce had some wg on my shelf so i broke it ou yesterday and detailed my 05 150. The color is silver. Fisrt i washed with pennacle bodywash, clayed, ssr2, fpII, wolfgang prewax gloss enhanser, then the sealant. It was a little harder to use than the upp, but not much. It gave it more of a carnuaba look. My question is can it be layered? Im planning on topping it with either paste glaze or sourvean.thanks.
