I'd bet good money it contains polymers which both swell clearcoats (around scratches/marks) and fill. They even use a word that is meaningless (i.e. they made it up) that references polymer content: "while a special blend of polymeroxane fluids and hydrophenolic lubricants attaches a microscopic layer of LumiShield-41 to the surface." There is no such word as "polymeroxane" of course, but it would appear to be referring to dioxane combined with polymers. Nothing wrong with polymers since those are pretty much the only way products like this one have a chance at swelling the clear coat and filling the scratches and marks -- typical of similar products too. There is no free lunch nor magic as it comes down to a very basic chemical and mechanical process to properly polish a clear coat finish.
