I have repainted my Sunrasias in "Appliance White" looks okay IMO. Used a brand called Plasti-Kote comes in Spray Cans. I think 2-3 cans were enough for 4 wheels, no idea of original.
It will be hard to match the old paint which is no doubt faded but you can try. Or are you planning on a complete respray?
I'm not a fan of the textured stuff, but many are.
A good 2 Pac is my choice.
Paint the whole lot in the same paint but then in places like battery boxes you can add some extra protection.
