As it relates to coatings, products like OptCoat, CQuartz Finest, Modesta are a great way to protect the finish. I'm a fan of nano technology such as CQuartz and Modesta. IMHO, they provide better shine, depth, and gloss than opticoat. I've seen all three on several cars. We apply the latter 2 at our studio. As far as warranty, installer network, and customer support, CQuartz network is by far the best. It's important to remember though, to make sure you know EXACTLY what coating is applied and what steps are taken to apply it. The paint needs to be near flawless as it relates to swirls and scratches before any of the above coatings are applied. So, make sure you have a qualified installer that specializes in Teslas and is aware of the paint issues relating to YOUR car.
As jerry mentioned, the best level of protection would be a self-healing clear film such as XPEL Ultimate or Suntek Topcoated. This is going to cost more, and finding the right installer is even more important. The film is applied over the paint, and it protects against rock chips, scuffs, door dings, and vandalism. The other perk is that the material is self-healing...this means no swirls or scratches. If installed correctly, it's almost undetectable.
Hope this helps
