This is my experience with Zeps on a 23 year old MH. After about 15 years in the sun I could no longer hand polish to get a shine, so I decided to try the Zep process. After cleaning with the bar keepers friend I noticed most of the oxidation came off fairly easily so I decided to try a paste wax and it took a shine. After 2 more years it would no longer shine up so I used the Zeps wax. It never yellowed and I only used 3 or 4 very thin coats. Thicker coats caused flaking where I used too much on the front cap. Knowing this I let the sides and rear cap wear off for several years before reapplying the wax. It will wear off in the elements not like a inside floor. The sides and rear cap have never been stripped. The front was stripped several times due to cleaning the bugs of with a diluted form of Awesome. MH still shines. Zeps is an acrylic and will not adhere well to a shiny surface and will flake off over time. I would not use it on a newer MH for that reason. It bonds well to a oxidized surface once the chalk is removed.
