The first thing I did on my new Jazz was protect the bodywork: Carbon Collective Molecule 9H Ceramic Coating - 5-year ceramic protection.
At a professional company it costs about 700 GBP for a new car and about 800-900 GBP for an older car. It cost me about 170 GBP + my labor.
A ten-hour "shift", I made it in one day, but I was still broken for two days. But thank God, it's done.
I put on a fair two coats and still had some left over.
The product description says it prevents scratches, which is nonsense, especially with such soft paintwork as Honda's.
But otherwise, it is good protection against UV radiation, dirt, maintains shine and repels water.
The good thing about this product is that it is for practically all surfaces, so I have used it not only on the bodywork, but also on glass, plastics, wheels. In fact, I now even have "liquid wipers".
I did this in May, a month after buying the Jazz. Interestingly, even a relatively new car (manufactured in November 2024, imported to my country in January 2025) had already caught a lot of dirt on the paintwork, the deIRONizer worked well, I didn't expect so many places with flying rust, it wasn't just a few spots, but the entire body was covered.
