I'll tell you why this is sketchy or at best, not well described in their ad:
Take these two quotes:
"This new product allows you to coat products other than metals, such as: wood, plastic, ceramics, foam, etc."
&
"Cure temperatures will range from 300°F to 450°F, depending on the particular powder used"
I would like to see someone coat plastic or foam and then CURE it at 450 degrees. Seems like a good way to instantly melt your products.
I think the general idea here is to liquify your powder so that it can be applied
a.) without an electrical current
b.) without having to buy a powdercoating gun
c.) to get into smaller, more localized and detailed work
I just cant see why you wouldnt just use paint instead at that point??
As far as durability goes, this product uses standard powders that are no more durable than any other powder. The liquid for sale here is just the carrier I think.
