Hey Chiefxr6t, Im into my detailing and Ive used the above mentioned website for alot of my research, but the main thing with the P21 is that its a carnauba wax. Althought it gives a better and deeper shine, it actually doesnt last that long. My suggestion and what I do is use a paint sealant first such as Poorboy’s EXP or my fav atm Wolfgang Deep Gloss Paint Sealant which I polycharge and use with wolfgang pre wax polish. After I have used the sealant, I go to town with the wax, 2 or 3 coats depneding on how much I CBF Using a sealant alone wont give you that excellent deep gloss effect, but using wax alone doesnt give very good durability
