I used this once over a coat of Klasse DGS (I've since moved on from) just to see what the carnauba would do to appearance...(turned out I liked the sealant look better anyway). The durability was roughly 3 weeks for a DD that was not garaged. It didn't wear evenly, some panels lost it sooner, especially the sun beaten ones. It melted off fairly quickly, but the appearance was very nice. I think it was an extremely close comparison to Megs Carnauba Plus. Only difference was the Mother's had no polymers or cleaners in it. Very similar appearance and durability. I used it once and gave the rest to my father. It is pure C. so there's elbow grease to be used (if not using DA which I didn't have mine at time of use) and for length of longevity, I'd just as soon use some Collinite 845 which gives an even better appearance. I don't detail for a living, it's just a hobby. **All of this is just opinion and preference, I didn't say a word about coatings!.**
