I have heard that it yellows and peels off in pieces. Difficult to completely remove. Your experience?
Mine has been on the RV for several years with no peeling, no flaking, no yellowing. I typical do a Spring cleanup with a soap and water and then apply another thin coat of Zep by wiping with a dampened rag.
A couple of years ago I did have an issue with bug splatters that had dried on for months. I had to strip the nose of the RV and apply several thin coats of Zep.
There is a major issue and that is surface prep. Zep is not going to do well when applied over dirt, old paste wax or on an old, oxidized surface. I used wax stripper, then swabbed again with a pretty stiff ammonia solution. Finally I hand scrubbed the entire RV with a 3M scotch pad and Bar Keepers Friend. That sounds like lots of work but really that was not much more than it would take to hand apply a paste wax finish. After prep, I used a rag dampened with Zep to apply thin coats. It takes a minimum of two coats to get a decent shine and a couple more to build up the finish so it will last. I can say for sure it does last, year after year.
Zep also stops oxidation and bleaching of surface due to sunshine. The acrylics in Zep block UV light.
