Out with ZEP, but what for best protection and looks?

I put Zeps on my MH 3 years ago,still looks good. After I did I had to repair some caulking and cleaned the area first with acetone, off course it dripped and ran down the side and completely removed the Zep finish. I poured some more into a rag and remove the Zeps in the surrounding area them reapplied the Zeps. It blended in nicely with the original application. So my conclusion based on my experience is use the acetone it will work fast with little effort.
