Duragloss has a wax for non clearcoated paint. In my experience it doesn’t matter much. Wax that is safe for clear coated paint is also safe for non-clear coated paint.

edit: they do not. They do have one that’s a cleaner wax. I very much like it for just a wax, but I’ve never used it on single staged paint. All the cars that I’ve detailed that were single stage paint were also full details, so I really can’t say the wax was very important (ergo, if my advice is entirely practical).
