Do Coatings Have UV resistance?

[Oldfordisbetter]

have a tube of optimum gloss coat. Just wondering if something like this has UV inhibitors in it? How about the pro versions: they have it? Was checking out c quartz finest website and I didnt see anything mentioned about it. Maybe DR. G can chime in again. My question is do some of the coatings have any UV protection or are we relying on clearcoat for that?

It`s a good question. As I said before, I always thought OC did..or I recall it saying it on the claims. I have some 22ple around here I`ll have to look at and see what it says, if anything.

The line of Gtechniq products offers UV resistance. Check out their website and FAQ.

If coatings aren`t UV resistant, they`d essentially be worthless imo.

[Oldfordisbetter]

Silverfox, thats what I was thinking. I was pretty sure they were, just double checking. I wonder if all the PBMG ones are?

[TroyScherer]

The question I have is: Has anyone been able to show proof of UV resistance in actual documented testing?

^^^bingo. Thats why I am hoping Dr G can chime in and give some info on his products

I`m pretty sure they all claim to offer some amount of UV protection. Seeing some of the long term testings out there I believe the do indeed help. I forget which user it was that coated over CC failure on the deck lid of a car but it held up very well. Obviously being so thin I`d think it can only do so much though.

From seeing previous post, they do contain UV inhibitors. Products like Opti-Lens are supposed to have an even higher amount of them.

I believe it was Corey. I`m a little skeptical when people review their own products though.

I`ve used almost every popular coating out there. I put plenty coatings on headlights and NONE offer the UV protection of whatever the OEM coating is. All the coated headlight yellow way faster than the OEM. So I conclude the UV protection offered by coatings are marginal at best.

No, the one I`m thinking of was done in another country with OCP....I think it was "Kc`s" that did the testing...I`ll try and find it but the search function blows now for old threads.

Corey seems like a good guy, I just didn`t like the trouble that cquk put me through, but a lesson learned I guess

I am sure in many cases anything you apply to a vehicle provides UV resistance to some extent -- even dirt.

[Ronkh]

IMHO

I`d be very surprised if they didn`t have some uv protection. How much probably brand/style dependent. I also believe the newer paints also have uv inhibitors in it as well as plastics. ergo the problem when headlight restoration done, is that the coating is removed. When a coating is applied over it, it is less than at the beginning of the life cycle.

Just sorta my uneducated guesses.
