Ceramic works well over vinyl, including matte. While matte picks-up a little gloss, everything picks-up a LOT more gloss, so it works. Here are a couple shots of my Shelby, which has matte black stripes over gloss black paint, after ceramic coating everything...

FWIW, I coated my truck (including trim pieces) months ago and it still looks great. Prep the surfaces properly (as it sounds like you have), apply the product as directed (without over-applying), level as needed, and buff to great shine. Maintain with Graphene Detail Spray. Post some pics when you're done.

I remain interested, but weather look less than optimal, again. 😕

I, similarly, use one of those "cones" that goes on the end of a drill, along with metal polish. Be nice if Adam's offered some of those "balls" and/or "cones" for this...

In my experience, exhaust tips need a bit more "elbow grease" than you get with a woolie and APC. I've gotten better results hand polishing with Metal Polish and Edgeless Utility Towels. For heavily-soiled/stained tips, quicker and easier results are possible with mechanical solutions that, unfortunately, Adam's doesn't offer. I wouldn't worry too much about water in the exhaust, as long as we're not talking about a lot of it. One of the ingredients of exhaust itself is water, albeit vaporized water. Moreover, the exhaust sits lower than the engine, so engine damage is unlikely. All of that said, I recommend either inclining the car with the tailend down when rinsing the exhaust, or taking it for a drive when you're done.

I agree with @Rich - your paint need not be "perfect" for whatever LSP you choose to use. The important thing is that you're happy with the way it looks and that the surface is clean/prepped for LSP application, so it bonds properly. Whatever you choose - Ceramic Spray, Graphene Spray, Sealant, or Wax - should enhance shine, provide some protection for the (corrected) paint, and simplify cleaning.

Not sure I understand the "problem." I suggest adding more water to the buckets.

Aside from Eco All Purpose Cleaner, of which I'm not a fan, this mirrors my experience.

I haven't found anything that works better than cleaning, polishing, and ceramic coating them. They still get dirty, but cleanup is quicker and easier.

Given this clarification of your intended application, I recommend CS3 or Ceramic Waterless. Graphene Detail Spray and Ceramic Boost are less-than-optimal for this use. Agree with CS3, but don't think Graphene Detail Spray is a good option for the clarified application... "Unlike Adam's CS3, Graphene Detail Spray™ is designed to work best on a clean, freshly washed surface and is not intended to act as a type of waterless wash."

I agree with Michael's assessment, that Wheel Cleaner is not required as often with coated wheels. (I rely on a spray bottle of dilluted Car Shampoo most of the time.) That said, I've had no problems using it AS DIRECTED on multiple sets of ceramic coated wheels. The answer to your question is, therefore, you CAN use it as needed.

In addition to what Rich said and based on the title of this thread, I'd offer that I'm not a fan of original Detail Spray on top of ceramic. In my experience, it tends to leave a residue and streaks. I get better resutls with something designed for use with ceramic like Graphene Detail Spray, Ceramic Boost, CS3, etc.

Dave and Rich are spot-on. As usual, stick with the least aggressive approach that yields the result you want. I haven't seen it produced in years but, if you can find it, Adam's Clear Polish (designed and formulated for vinyl wraps and PPF) works well.

I've never had any problems polishing PPF, but I recommend sticking with the least aggressive approach that yields the result you want. I haven't seen it produced in years but, if you can find it, Adam's Clear Polish (designed and formulated for vinyl wraps and PPF) works well.

I agree, Jimmy! I'm a big fan of Adam's and the detailing products for which he and his company are known - have been for many years. Understand the desire to grow, but not when it comes with diversification into (largely) unrelated areas/products. (I get that detailing products and lubricants are both used on/in motor vehicles, but...) IMO, this results in brand dilution. There was a time when I proudly used nearly every product Adam's sold, but those days are long gone. I can't keep-up with the constant flow of new/different stuff, especially when it's not for detailing. I'm loyal to Adam's for my detailing needs and I like having autographed Adam's sign in my Man Cave, but I'm comfortable with Amsoil for my automotive lubrication needs. 🍻
