This is How Tough Car-Rep 2K Paints Are 

World's first 2-component 1-compartment can with unlimited potlife!
The Car-Rep® 2K Spray Paint System makes it easy to get a professional-looking finish on all your automotive projects with a full assortment of primers, clear coats, and stand alone color top coats all with the superior, corrosion, chemical, and UV resistant characteristics you can only get from 2K. But what makes Car-Rep products truly unique is the revolutionary, patented Wise 2K® Technology which features the 2-components (both the hardener and the resin) in a one-compartment can that allows the hardener to only activate once sprayed - not inside the can. This not only makes Car-Rep incredibly easy to use, but it also means our products have unlimited pot life - so you can use entire contents of each can with no wasted product.
