Dense automotive coating

I am planning to freshen up my car color soon, but would like to use a paint that is much denser and stronger than the basic options offered everywhere. What can you recommend?

Most likely you need to address such questions to the masters, as only they will be able to recommend you some options. But as for me, I would advise you to pay attention to such a coating as eveglass diamond. You can find a lot of useful information on this subject at https://everglass.co.uk/product/everglass-diamond-base/. Maybe this will be the solution to your question.
