You absolutely do not know what you are talking about. You are also misrepresenting quite a number of things.
You've obviously never worked in the automotive refinish industry. It's also quite apparent that you do not have any experience or knowledge in regards to the automotive detailing industry. I have extensive experience in both.
It's quite appropriate that the video you attempted to use above to propagate your claims in fact refutes them in the end.
1. Nobody has stated that the UV inhibitors in waxes and sealants is comparable to that of a clear coat! That is why they have to be applied regularly. They are present however and waxes/sealants offer protection beyond UV.
2. Modern clear coats are still put on cars as the protective layer. They are also still highly subjective to failure with improper care. I could easily walk you around a parking lot and point out a high percentage of clear coat degradation on many "modern" vehicles. You can claim whatever you want to claim but it's out of ignorance. Any professional in the refinish or detailing industry would laugh you off their forum.
3. You state that modern clear coats don't need a
"sacrificial layer" by citing Dmitry's YouTube video. Yet, in his conclusion starting at 13:00, he in fact agrees that waxes and sealants do act as a sacrificial layer for the clear coat! He does this by citing Mike Phillips of Meguirs
"...if you wash and wax your car regularly, your paint will be protected and you should suffer no major UV damage over the normal course of the life of the car..."
I don't know who this Dmitry is but I guarantee you he isn't remotely as knowledgeable as Mike Phillips. That is why he is sourcing and quoting Mike Phillips. I use Meguiars products and I've conversed with Mike Phillips many times in regards to the detail industry.
Dmitry then emphatically says
"It is actually very clear how much waxes protect clear coat especially good waxes and good coatings....this is why the wax is so important. It provides that sacrificial layer that keeps your clear coat safe".
So, your definitive source flatly refutes you here. Dmitry then notes the flaws with his testing method
"Through the UV exposure testing that I am doing, the process is very rapid. I am not allowing for a very fine measurement....although these products may be providing a little bit of UV protection....It's hard for me to measure the impact over a long time".
This is in fact the major flaw with his testing methodology. This flaw was in fact brought to his attention by Optimun in another video of his, as sealants and waxes have a
cumulative effect. You do not get an accurate result on glass after one application as he tested and as he tested at the wrong spectrum in that particular video. You get the most protection by washing your vehicle on a regular basis and by frequently applying a wax and/or sealant to the vehicle, as I and others have correctly recommended!
He was then properly educated in another video by a poster on how sunscreens and waxes are effective in regards to UV protection. To his credit, he appreciated the insight.
In Dmitry's defense with the video you linked. His point in the video was to show that waxes and sealants offer very little UV protection in comparison to a clear coat. He is absolutely correct there. You however went a step further by attempting to suggest waxes and sealants offer no protection and as such are ineffective, which is absurd.
