Scott hit the head of the nail on that one. I frequently (when needed) use SSR3 followed by DACP. If I were to follow SSR3 with SSR1, I would need to do it twice to get the results I desire, or as Jim suggested, using Pro Polish.
As for general swirls, I think you are safe using DACP, followed by a final polish like Mullet Wax Awesome Polish, Poorboy's SSR1 or Pro Polish, or Adam's Revive just to name a few.
