Now this maybe a stupid theory or even question but if Sealant or wax (which ever is preffered by user) is applied to the windshield or any other glass surrounding the vehicle, would it therefore be blocking UV rays from getting into the cabin which could cause damage to the dash, interior, etc. This whole idea popped into my head the other day as i was sealing the paint on my car. If the sealant is creating a barrier between your paint and the environment and is shielding uv rays to contact the paint surface then it would to block uv from going past the glass? Someone please chime in! I know this may sound stupid!
 
I don't know how you would even know if a "sealant or wax" is protecting your paint from UV rays. Cover or shade of some sort is the only sun protection I trust on any surface.
 
Well im going based of description on the bottle. Stating it blocks UV a and UV b. So if it indeed does block then that's where my question was headed. lol

-What is the actual name of the product that's in this bottle?

BTW:
-It's the thermal heat that'll kill a vehicle's cabin appointments faster, more so, than UV-rays.

I also lean towards, and agree with the following:

Understood.

Probably better to say that laminated auto-glass (think windshield) is the best at "blocking"
UV-rays (A, B, or C) up ~98%---more if the piece of plastic, that's sandwiched between the two pieces of glass, has more UV blockers added.

The other auto-glass is usually of one-piece, that's been tempered. This type of auto-glass "blocks" ~60% of UV.

There is a push by organizations to have autos equipped with more laminated glass for occupants accident protection, and UV safety reasons.
Here's one group that keeps track of this: Welcome to EPGAA.com


At the end of the day:
There's still that dang IR to contend with.

I remember trying out PL on my windshield and when I washed it, it worked great on sheeting. However, in the morning with the morning mildew it would haze up dramatically. Which lead me to not use PL on the windshield again.

my car's windshield does have Opti Coat and while it is not designed for windshields, I have found it to due a phenomenal job.
 
Sealant or wax will come off of your windshield very quickly due to the wipers.

According to the description on most of my sealants it does protect protect the paint from harmful UV rays.
I'm no chemist but I do trust major companies that claim it does have UV protection.

Same here, never ever again! My issue came during a rain storm. Windshield became almost opaque for several minutes. Annoying and dangerous!

There are several major detailing companies who are repeatedly caught in lies about products and practices, most especially about manufacturing their own products. I would take most scientific claims with a pinch of salt as it is well known that the guys marketing products often say whatever will appeal to the consumer. With no actual link to the science, there are endless examples of scientific claims being blatantly incorrect.
