Wouldn't WD40 strip off the ceramic coat?
Ceramic is supposed to be chemical resistance once cured, so it shouldn't. I have not noticed any issues on my PPF or ceramic areas where I had to use it. I tried to avoid it initially but the marring was worse from trying to polish or lift it other ways. WD-40 disolves it so you don't even have to scrub. Most "bug and tar" removers are similar - a petroleum distillate of some sort that just eats the tar/rubber.
