I am in the process of giving my car an exterior detail and have a question regarding combining Klasse AIO with Klasse SG and/or P21S Concours carnauba wax. I started with a clay bar, then went straight to applying Klasse AIO since the paint was in great shape and didn't really need polishing. Now I am wondering if I should follow that with both a coat of Klasse SG and a coat of P21S wax. This is my first time using the AIO, so I am not sure if following it with the SG would be redundant (doesn't the AIO have sealant in it?), or if I should just skip straight to the wax. Is there still benefit in applying a layer of the Klasse SG AND finishing with P21S wax? Last year I polished the car with Menzerna SF4000, then did a coat of Klasse SG, then 2 coats of P21S wax. But for some reason the results weren't as great as I was expecting (not as glossy?), maybe I put the sealant or wax on too thick or something. Any help is appreciated. Thanks.
