Need help understanding on how waxes, coatings etc protect paint

[MrOneEyedBoh]

So I was driving to work one day and I was thinking... How does wax, sealants, coatings etc protect paint? Mainly what I want to understand is how it protects paint from UV rays?

How does it inhibit damage or is that what we were told and are to expect? But in reality it's jot actually doing much? It's hard to believe a coating can protect longer and better than a wax that is applied every 3 months or so. But with that even aside, does it even prolong the paint's life?

I dont think waxes or sealants actually protect from UV, or if they do it would be very minimal. They are a sacrificial barrier that protects the clear coat which is the layer of paint that contains UV stabilisers to protect the colour coat. Waxes and sealants protect the UV protection if that makes sense.

Yes, waxes coatings and sealants definitely prolong the life of the paint because they are destroyed by the elements rather than the paint, this is why they have to be reapplied. They take the bullet for the paint which in turn leads to no or very low damage to the paint.

Optimum Spray wax is said to have patented UVB and UVA protection.

Optimum Car Wax is a spray wax made with real carnauba and synthetic paint sealants for protection & shine! high-grade carnauba wax and silicone

There was a nice experiment done to test this. See this thread: http://www.8thcivic.com/forums/showthread.php?t=249235

I wonder how much coatings do after having read this.

This is probably TMI for most people here but I have an engineering and chemistry background by education, training and experience so my curiosity of these products is high. Regarding UV protection I am very fascinated by the chemistry applied to this problem. A link to one of David Ghodoussi's patents https://www.google.com/patents/US6685765 discloses an amazing amount of technical information about the design and composition of what is probably the formula for Optimum spray wax. In effect, this is a disclosure describing much of how Optimum Spray Wax is composed.

The amazing thing is the patent disclosure has citations for many chemical products that are available. Here are two specifically cited as UV inhibitors:

I would have liked to see that same test done with sunscreen mineral based and chemical based on the same glass and see what results are. If there were the same results there even though it could not absorb into the glass at least the chemical sunscreen could be a oily looking mess on the glass to see if that blocked any

Obviously TMI.

Obviously TMI.

That all you have?

You bore me---watching you:
so reliant on condescension;
reeling towards the inevitable
apotheosis of desperation.
