General question

Hello dear car paint maintainer, a question in the round, what do you take as varnish sealer. I have already tried a lot and wanted to ask you some questions what you used exactly. It should be a little firm and of course also a little shiny 😉 What I used already: Scholl Concepts W09 Premium Soft99 fusso coat menzerna power lock ultimate protection menzerna carnauba protection MEGUIARS WACHS NXT TECH WAX Greeting
