Excellent job! I need to invest in a decent ceramic coating sealant or lok into a good recommened detailer.
There’s certainly excellent choices of ceramic coatings. Some are pro only application, such as Gtechniq Crystal Serum, but plenty can be applied yourself (with some care) such as Gyeon coatings. I guess it depends whether you prefer to have the car sorted by a pro detailer or have a go yourself. I’m in the latter category and wax is my pref, but whatever you choose, a good choice of protection and importantly, good prep, will make the car much easier to maintain.
