DuPont sold their paint lines to a company in 2013 for $5B. Axalta is a brand name I see, depending on the jobber, that I am pretty sure is related.
If you want single stage with hardener there has to be an economy line. You have the hardener, try a BASF/Glasurit jobber. They would have LIMCO which catches (verbal) crap all the time but is a very stout/not too expensive paint for less exotic stuff.
I painted this last year with LIMCO. Maybe $400 per gallon.
