The Medallion works quite well for me, mainly because the cleaning action seems to be just enough to maintain what is there and not cause the swirly, (like that?) look that a wax build-up can cause.

The question I have, if I use a carnauba over that, (I did, and it looks really great), will the Medallion last for several months like some of the polymer based sealants? Will I need to apply more Medallion and then the carnauba over it each time I detail my car?

Will just more carnauba every few weeks work? Do I just need to try it and see what happens? The car is a daily driver, but is well cared for and garaged much of the time. It is washed anytime it is dirty and waxed at least monthly.
