Since you mentioned quality over price, let me clarify what "quality" actually means in ceramic coating: the implementation of best practice methods, the use of best products and verification of results with scientific/analytical methods.

The key differentiator is whether a shop can measure and prove performance rather than just make marketing claims. Most shops rely on "year ratings" (5-year, 7-year, 9-year) which are essentially meaningless without actual data to back them up.

At CeramicFX (Dallas metro), we measure contact angles before application, immediately after, and track performance over years. With this capability, we are probably within the first 0.1% of coating installers in the world. Real data, not marketing promises.

There's actually a very relevant discussion happening right now about exactly this topic - Choosing the right ceramic coating company — 5, 7, 9 year claims?

This will give you a much better understanding of what questions to ask any shop you're considering and why scientific measurement matters more than star ratings.
