I used two stage. I used an exterior touch up gun. Yes, I know the original is single stage lacquer, but the basecoat with vintage clear is hard and durable. I mentioned the Vintage clear when we discussed engine compartment paint. The Vintage Clear uses an activator that the quantity controls the sheen. It can be sprayed flat, eggshell or semi gloss. It's VERY durable once cured. My Shelby is not going to be a trailer queen and being it's a version of white, I know it will be cleaned often.
