I had CQuartz Finest applied to my car about 3 years ago. It is a great product, but I am wondering after 3 years if I should try and remove it, and reapply something else? It only has a warranty of 2 years and I am obviously out of that window. It still seems to be doing its job as good as it did when it was applied. Or should I just leave it alone and continue to do regular maintenance as needed? I really like the idea of having a "extra layer" to protect the clear coat from scratching, etching, etc.
