When you apply wax on top of the ceramic then you have the qualities of the wax not the ceramic. Wax is no longer necessary or the superior product. It washes away, it does not provide the self cleaning that ceramic does and that is part of the reason you applied the ceramic to begain with. Also the only thing you have to do to the ceramic is wipe it down every 3 - 6 months with the suggested spray "reload" product. I was very skeptical about ceramic but my bike and GMC both were ceramic coated in Aug 18, The only thing done since was at the 6 & 12 month windows I wiped them down with SI02 and both look like they were coated yesterday. I just cannot see why you would apply any wax on top of this great product.
Pinnacle, that you mention, is a House product of Autogeek, I buy lots of stuff from Autogeek and think Mike is very knowledgeable but they also sell Blackfire, which I used in the past. Most folks that live over on that coast say both products are the same, just different names. Autogeek does not have a lab etc. Not to say products are bad, they just are outdated. Also cost of quality waxes are no longer necessary. I bought and coated a new car earlier this year, I used CarPro CQUK 3.0. It is amazing, car is black metallic and looks WET all the time, doesn't attrack dust and when driven in the rain it hardly gets dirty, just to slick for dirt to stick. I just can not imagine giving up all the qualities of this great product for wax again and if you wax ceramic you might as well just wax to began with. And the best thing is CarPro with everything you need to install is $63 from Amazon, wipe it on with the applicator supplied then immediately buff off with a 360GSM microfiber and all I have to do is wipe down with spray suggested by CarPro every 3 - 6 months? No more wax for me.
If you research Ceramic coatings, none of the companies I know of suggest wax topper, most suggest you do not.
Also you can use Iron-X on your Ceramic coating to remove brake dust & road crap without hurting the ceramic and it will completely strip the wax.
