Our professional grade ceramic coatings are applied to the exterior surfaces of the vehicle after careful preparation. Ceramic coatings bond with the exterior surfaces of the vehicle to form an additional layer of defense against the elements; protection from UV rays, oxidation, insect contaminants and environmental pollutants. The result is a beautiful ultra-slick hydrophobic high gloss surface that and easy to clean and lasts for years with proper maintenance.


We offer top-quality XPEL PRIME XR PLUS™, XPEL PRIME XR™ and PRIME CS™ window tint films for superior heat rejection, UV protection, and glare reduction. Our ceramic particle technology effectively filters out the sun’s infrared radiation, keeping your interior cool and improving fuel efficiency. Both window tint films are recommended by The Skin Cancer Foundation as effective UV protectants and do not interfere with radio, cellular, or Bluetooth signals.

Just wanted to give a huge shoutout to Knox Details. They laid down some XPEL Paint Protection Film for me on my wife’s 2021 Toyota Highlander. These guys have been great to deal with from the first phone call, through the install, all the way to the pickup. They did a great job and I cannot be more satisfied. Huge thank you to Tim Buxton and the installer Thomas. Hit up Knox Details for all of your detailing, and paint protection needs!

After a ton of research we chose Knox Details to get our 2017 Porsche Panamera protected and what a great choice!!  Tim and his staff were very professional and exceptionally knowledgeable in all my questions.  We had the front-end full PPF, ceramic coated and detailed the interior at a great price!  Any and all concerns were put to rest when we picked up the car.  Looks AWESOME!!  I can’t wait to get my 2018 Z06 done!!  Thanks Knox Details

I was very impressed with Knox Details. My car looks better then expected. My car is 10 yrs old and getting traded in within a couple years. I didn’t want to sink a bunch of money into it, so I went with a cheaper service. Yes, there are still defects,  but the car looks better than I thought it would. Defects I expected to be noticeable are not. Defects I expected to be very visible are there because I know to look for them. I am very happy with the service I received. Jordan even went above and beyond on an unrelated issue. As someone that has worked in customer service for 20+ years, I was impressed.

Fantastic job on our new Buick Envision Avenir pretty much can’t see where the film starts and ends.
We are very pleased thank you Knox Details.

Tim and his team are bar far the best at what they do in east TN. We’ve have them do two cars and I won’t go anywhere else. It’s not the closest place to me nor is he going to be the cheapest but you get what you pay for. Thanks again Tim!!
