Last Coat is a Si02 based product. Makes great shine, has so-so lasting abilities. Graphene is quickly pusing the products like Last Coat out of favor. The new Turtle Wax Graphene, or even the existing Turtle Wax Spray Ceramic is a more advanced, much cheaper product than Last Coat and will outlast it. Check out Pan the Organizer on YouTube, he tests them all, Last Coat was great, a couple years ago. No longer top of the line and still costs to much.
These products make crazy shine, but they shine what is there, If surface is scratched it will be shiny scratches when you get done. NO cleaning or abrasives in any of these ceramic or graphene products. But Crazy Shine, water beading and dust repellant.
