Epoxy polyamide in lusterless black (37038) is readily available at $195 for a two gallon kit. This is NOT so called epoxy in a spray can. This is a 1 gallon bucket of resin and a one gallon bucket of catalyst - a true epoxy paint.

Not cheap but readily available and extremely chemical resistant.
If you have any doubts the chemical, corrosion and abrasion resistance performance requirements are readily available and your can compare them to your favorite.
