This is my opinion after using professionally getting ceramic coating applied on 2 cars including the truck.
You still have to maintain them, regularly, put toppers on them, can’t use clay (highly debatable topic abut most agree to stick to chemical decon). Do they give some extra pop? Yeah. Is it worth 1200-1500 USD? No in my opinion. On my truck the coating failed, either due to me not maintaining properly OR put in wrong, whatever the case may be, recently I applied 2 coats of turtle wax ceramic spray coating, washed every week in summer with a topper , I see same results. Winter up here I try to wash it as much as I can but inside the garage without a floor drain you can only do so much. In spring I will do the routine maintenance of chemical decon and may be clay if needed and it’s all good. I have personally decided not to spend the obnoxious amount of money on coatings anymore. Every 2 years or so, I will either do a single stage compound/polish and get the so called consumer version of coating installed by me, or get someone to do the polish and do the coating myself.
Your mileage may vary.
