So Rustoleum's lawn furniture Enamel.
There is a recoat window on most all spray can Enamels, and adhesion after the Enamel cures varies with product and the finish you are spraying over. So a satin black will need to be sanded or chemically prepped before a new coat of any paint can be applied to cut down the sheen/gloss so the final paint coat will adhere. If that's the route you're taking, I suggest using a flat black for your base color coat for better overall clear enamel adhesion.
