I haven't used it, but I looked into it pretty well. It's a two part deal, both in spray cans. The first one can be considered a 'primer'. After that has set up and cured the second can is used to apply a top coat. It goes on with a semi transparent finish, think of it as a whitish foggy coating. It applies like spray paint, but it doesn't hold up in the same manner. It will 'wear away' or 'dissipate' like an oil film will. A little slower mind you, but it will disappear to the point that it will need to be reapplied again. Canadian Tire sells it for around 25.00 for the kit. States side it goes for 20.00. Menard's in Port Huron has it on sale this week for 14.00 per kit. If they could get it to act more like paint and have a clear finish coat (or solid colours) they would really be on to something. There was a challenge by the manufacture to the general public come up with uses for it beside what they have. Kind of like...well we invented this stuff, but we don't know what to do with it.
