The rattle can crap is usually a mix of oil/and water base paint to stay separated and achieve the look and will need to be cleared.

Zolatone is specically designed and does not need a clear, they do have a catalyst that hardens it further and makes it more durable.

I would choose a similar/maybe not "correct" color and still use the Zolatone brand paint because it is so durable and looks much nicer than rattle can.
