How would some of us novice detailers conduct our own product testing of waxes and sealants? Shine is easy to see right off, but I am just as concerned with durability. How do I tell when UPP or EX has worn off my finish? They both have polys and they protect even though they don`t always bead. The carnuba in EX is mostly for shine and beading, right? Someone mentioned once that Gold Class, for example, has some polymers in it, so even though after a while it no longer beads, but it still protects.
