I use duplicolor engine paint in black semi gloss ford engine paint.It goes on smooth as with a gun ,holds up good and dries fast.The semi gloss looks close to factory to me.Walmart only has the flat and the gloss so,I get the semi gloss at either napa or advance.The duplicolor is engine paint so its oil and gas resistant.If you want epoxy paint at walmart you could try the appliance paint but Im not sure if it comes in anything besides white or tan.
