This weekend I tried both of the Menzerna polishes by hand. It seems these will work much better with a PC, I will get back with that info soon. I didn't need the intensive but I tried it on one panel. Very easy to use with more gloss than most cleansers, well it does say it is a polish. The final polish, was very difficult to remove, so if that is a problem for you don't use this. For me it was well worth the work, very nice gloss, not really deep but bright and clear. This product doesn't really compare to something like #7 or GEPC as it has a different effect. It is almost like a very thin layer of glass on your car. I followed this up with AIO and then UPP, the car is stunning. Although I need some more experience with the Menzerna products to fully evaluate them and their best applications, I think they can be a great addition to your detailing arsenal especially if you are using polymers and a PC.
