After reading reviews of "Renaissance Wax" on prints, I don't think they meant
untreated inkjet prints.
The stuff soaks into the inkjet coating pretty well and can darken whites permanently. It can be almost impossible to remove if you do an area larger than 2x2 inches as it dries that quick and hardens. I tried several paper surfaces and just no luck.
What did make a difference was to coat them with McDonald's SureGuard Pro-Tecta-Cote lacquer and then follow it with the above wax. The wax then was much easier to apply and easier to remove and buff out with a terrycloth towel. It didn't have the issue of soaking into the print surface and discoloring it either. I just used a cotton ball to apply the wax, then buffed it within 30 seconds with the terrycloth. Works pretty well.
Fwiw, if you do not know how to work a spray can this guy is a riot! Some of it is relevant even for inkjet prints.
