The Liquid Lustre sales rep which demoed the product didn't use that type of sales pitch (lighting fires or acid). What he did was use a hood (red) set up under 4 sets of halogen work lights and applied the product. The product applied and removed easily. He did the obligatory clean your house key. He showed the sheeting action. At the time (several years ago) the price was, I think, $15 for 2 16 oz bottles of product and for another $5 you got a third 16 oz bottle. I was dazzled by the SHINY red hood glowing under the bright lights, I paid the man my $20.
As I said earlier, I have not been that disappointed in my purchase. The product went a long ways and provided a very decent shine, for a one step product. I have since come across many products which I favor over the Liquid Lustre. Most requiring more than one step, though. Until I deplete the last of my product, I won't be above slapping a coat on my daughter's, son's, or Father-In-Law's vehicles.
