I used it by itself on the back bumper/wrap around of wife`s Civic last year. When I coated it with Zipang-Miyabi-Zipang (June 2019), left that area uncoated as some wobbly sausage had whacked the lower right rear area of the car sometime during Winter and I was gonna be touching up a chip or 2. I used Infinity Wax + Overcoat to get me through the Summer and on into the Winter/Spring of 2020. Did quite well for the Summer months, about 3-4 months in it started to `not hold onto the Overcoat` as well, needing more frequent applications. It was totally gone I`m sure by the time Spring 2020 rolled around, probably sooner. I`d guess in nice weather with Overcoat on occasion it`s a 4-5 month deal, maybe a bit longer if actually maintained frequently which this car is not. This car is very lightly used as wife only works maybe 5 miles from home, no freeways; generally just sits outside getting covered in pollen, leaves, rain and whatever else falls from the sky.

The Kami Infinity Wax is definitely tougher than PA High Gloss Paste though, that much I can see already. Better water behavior as well; it`s pretty great on it`s own but the Overcoat on top adds a bit more without diminishing the look. But you know how that whole `appearance` thing goes...it may be all in my head!
