The benefit of using a two-part finish, such a Duracoat (or Sherwin Williams Prolane T), or Cerakote H and E, is the chemical resistance you get that cannot be matched by a single part coating. Pretty darn durable too when done right. Degrease anything. Scrubbing with Dawn will work.

For your proposed use there's nothing wrong with Krylon or any number of other spray can finishes like Rustoleum 2X camo line, or Hunter's Specialty. Even better an epoxy coating like Brownell's Aluma-Hyde. And some clear, good stuff not some crafting product, on top is always more durable than a color, likely more chemical resistant as well.

Krylon Fusion is specifically formulated to adhere to plastics. Using an adhesion promoter like Bulldog is the best assurance for a chemical bond prior to any of these mentioned. Usually there's spray can plastic adhesion promoters in the autoparts paint section.
