Thanks for the response!
I do my cars detailing myself as an amateur

-- clay, polish, and sealant but newer did go into the ceramic coating land.
I did some lookup in the past and there are always a horror stories even for the best rated ceramic coats. It is also tricky -- you might wipe it out almost completely and believe that you have a coat layer when in fact it might be gone in a few weeks. Also, many ceramic coating compounds are not suitable for chrome and might just destroy it.
There are professional services of course, but in case of failure they also wash their hands so to speak.
Some references I saw recommend using the "normal" clear coat polish as a protectant for black chrome, so I am considering this option as well.
It would be really helpful if other owners would chime in on this too.
Do you apply ceramic coating yourself and if yes, do you have positive experience on prior cars, and can recommend a particular brand which works well for chrome, or do you use professional service for coating?
