Wax gets my vote.
I worked for a chemical manufacturer for a number of years, and floor finishes were one of the things we actually made. And Zep products were some of our competition, along with Proctor and Gamble, etc.
The zep product is a floor finish and designed to be applied to asphalt tile (like what you see in grocery stores. It has zero UV protection. It is not rated for use outdoors, period.
With that being said, I understand how some people are trying to bring back faded materials. Zep may be the only way to do that. However, for a new TT, I would go wax all the way.
I would use Collonite 845. It is amazingly easy to apply. It, however, is not a cleaner wax.
