There's a number of great polishing systems out there today made by numerous manufacturers. Optimum, Griots Boss System, and numerous others.
Quite likely as has been rumored, the Wolfgang line, and probably other Autogeek PBMG brands have polishes manufactured by Menzera.
Their selections of polishes may not be as vast as Menzerna though. That can be confusing too. Menz 3500 will be an optimal last step polish for getting every last little bit of gloss from the paint. Usually such polishes as this are intended to be used with the least aggressive pads. 3500 is not particularly intended for deeper RIDS (Random Isolated Defects) removal.
In the Wolfgang line-up, probably what would be closely similar to 3500 would be WG Finishing Glaze.
Wolfgang Uber is sort of in a class of its own, a sort of "hybrid polish", consisting of both SMAT (Super Micro Abrasive Technology) and DAT (Diminishing Abrasive Technology)
Uber starts out acting like a more aggressive "compound" and the larger abrasive clusters break down and diminish, getting finer and finer as the product is worked. It then mimics a very fine finishing polish as it breaks down and is worked.
Besides Menz 3500, if this is the one you will choose, I might also consider one that's slightly more aggressive to also have on hand within their line-up.
