That is the main reason I was thinking of ceramic products. By the way, I am new to a detail world. Is it okay to just wash a car and use spray wax before the ceramic spray coating? Because my car surface is not rough (due to wash every 2-3 weeks). I want a ceramic spray coating to prevent my car from oxidation and yellow headlights. I know it will not happen for at least 6-7 years but my old car had yellow headlights and totally killed the look.
