I cannot guarantee that Renaissance wax is specifically compatible with Waterlox. I just know that I haven't had any problems with it. Craft Supplies and Klingspors carry it. A little goes a long way, which is good because a tiny can is over $25. I typically wait until I'm reasonably confident that any topcoat has cured before applying wax. I give Waterlox at least 24 hours. Unlike many paste waxes, Renaissance dries very quickly and buffs out easily by hand. This makes it easy to reapply a coat if the need arises. As a bonus, it has a tolerable aroma.
That's my 2-cents worth, which might be overpriced.
