Looking for a top coat/ clear coat

[theadobesmurf]

I am looking for a spray paint top/ clear coat for my toolbox I am resurfacing. I used a rust-oleum primer, and then a rust-oleum painters pro (yes i know wrong paint but long story not very durable.

I am looking for a clear coat to for the outside of the drawers and the outside of the box. I am looking for something if possible to help protect the paint durability wise. I have looked into rust-oleum clear enamel but the main complaint I have seen with it is it takes forever to dry.

Looking for suggestions.
