Should I use Chassis Black Finish coating or AG111?

Chassis Black Finish Coating is a strong topcoat mostly used on the chassis of a vehicle. It is one part, no hardener needed, and can be brushed, rolled, or sprayed. It is not as durable and chemical resistant as the AG111, but is a still a durable topcoat for strictly under the vehicle. It is not UV stable and comes only in gloss black where AG111 comes in gloss black, satin black, gloss clear, and a few gloss colors.
