Hardener for acrylics?

[Monty]

I noticed that MCW paints offers a hardener to go along with their line of enamel paints and I've seen some YouTube videos of builds that utilized them together with outstanding results.  IMNSHO, there's no need for a clearcoat as the resultant finish looks like freshly polished paint.  

This made me wonder if anybody offered a hardener that could be added to acrylic paints.  I've heard (don't know for sure) that acrylic finishes aren't tough as enamels or lacquers so I'd like to improve on that if possible.

I've never used it, as I rely on smelly old-school solvent-based finishing materials.

I KNOW NOTHING ABOUT ACRYLIC PAINTS FOR HOBBY USE OTHER THAN ARTISTS' COLORS

HOWEVER...this company manufactures a line of acrylic paints for leather, and ALSO offers two hardener additives for enhancing adhesion to hard plastics and increasing film toughness.

I have no idea if they'll work in whatever acrylic paint you're using, but they're not very expensive, so some experimentation might get you what you need...or not.
