Need help understanding on how waxes, coatings etc protect paint

Interesting discussion here ... So yeah. Looks like a no. That's where I was and have been at . I don't see how a layer that is clear essentially, can repel UV rays.

Either way, I'll still do it for the obvious reasons.

I don't find it so hard to believe.. I think it's a bigger surprise that sunglasses are said to protect from UV light, considering they're a black tint and black is known to get hotter than any other color.
 
Via google you can find lots of information regarding how UV rays work and what can be done to stop them.

It appears that you can reflect and absorb UV rays. See below, copied this from a site via google---

"Sunscreens, which can be sprays, lotions, gels or waxes, are usually made up of a mix of chemicals. Inorganic chemicals in sunscreen can reflect or scatter the light away from the skin, and organic (carbon-based) ones can absorb UV rays so that our skin doesn't."

So I guess I was wrong---I guess that inorganic and organic materials used in waxes, sealants probably do absorb and reflect UV rays before hitting the clear coat and base coat.

Same deal with sunglasses---have materials to reflect and absorb...

The technology described in Dr. G's patent related to Optimum spray wax takes advantage of absorption. One of the products he cites is here:

From the product sheet:

Application guidelines
Tinuvin CarboProtect is a solid UV absorber, designed for solventborne coatings. While it was originally developed to stabilize carbon fiber
reinforced epoxy, it is also suitable for coatings, laminates and plastic substrates as well as base coatings requiring strong protection both in the UV-A range and near visible spectral range.
