2016 VEGAS here and we have started using REJEX. It is not a wax, but a polymer protectant.
Makes it to where bugs, dirt and streaks just wipe off..
It also gives a shine that is better than when we drove the coach off the lot.
Wish I hadn't waited almost a year to start using it. If it looks this good now I wonder what it would look like if I had used it from day one.
It is also easy to apply.
