Hi guys. For over 30 years I've always used Liquid Glass on all my vehicles. I've never been disappointed by the product protection, shine, or smoothness. People always comment on my show cars asking if I've repainted recently.
Anyways, my question to all of you is...has anyone used, and if so, what were your thoughts on any of the new products being advertised, IE: Topcoat F11, Alien Waterless (claims to be an acrylic spray rather than silicone), any of the do it yourself 9H coatings, etc?
