I have read about peaple using floor polish, but also about it flaking off.......

If the ZEP surface flakes, cracks or deteriorates, it is a sign of poor surface prep. Before using ZEP, I stripped previous coats of wax with a mop and an ammonia solution. I went over the RV twice. I also used a Scotch pad and some bar keepers friend to lightly scrub the entire surface. I might have been excessive but my original ZEP coating has lasted for years and still looks absolutely new.
