Can epoxy primer be used over Rustoleum rattle can gloss black paint?

Like I said earlier I'm going to do a small test area before I decide what to do. The car is going to be painted bright red and I would like the engine bay to be the same color as the body. Hell Rustoleum makes a really bright red I may do the engine bay with that and have the paint shop mix some paint to match for the rest of the car.
