What's the difference between AG111 and Chassis Black coating?

AG111 is a two component coating and Chassis Black coating is a single component, no hardener needed. AG111 comes in gloss black, satin black, and a handful of colors like white, red, or gray. Chassis Black only comes in gloss black. AG111 is UV stable, but Chassis Black is not and should only be used where there is no sun exposure on the vehicle. Chassis Black is a durable and chemical resistant coating, but AG111 is even more durable and chemical resistant (as in, better for road salt protection) than Chassis Black. AG111 should be used for a more professional restoration whereas Chassis Black can be used if you simply want to brush or spray on a chassis to preserve it and you don't have to deal with such things as road salt in your region.
