Factory paint color for suspension/rear end housing

I really like Rustoleum Professional semi-gloss black 239107. Comes in a 15 oz. spray can and sold at Lowes stores. Takes a while to cure but very durable. Also available in quarts if you want to use a spray gun, and you can also catalyze it with Valspar 4725 enamel hardener (Amazon) if you have the proper respirator and desire a faster cure.
