Do Coatings Have UV resistance?

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.
 
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.

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.
 
I am sure in many cases anything you apply to a vehicle provides UV resistance to some extent -- even dirt.
 
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.
 
I think the real world tests (cars with coatings) have proved they have enough UV protection to last at least 2 years
I've coated many cars over the last couple of years and to this date have seen no failures (oxidation, clear coat failure) as of yet!
I agree with silverfox, they would be pointless to some extent without UV blockers

This is pretty interesting. Which ones did you see last the longest?

Well what if you just put a sealant on them? Would the sealant outlast the coating?

The OEM coatings are also sprayed on and likely 25-50 microns thick vs. 1-2microns with hand applied coatings, so I would expect them to have much less UV protection. From my understanding of headlight restoration you also have to fully remove the failing OEM coating before you apply a new coating, if you want it to last anyway.

I don't think that a CC failure would really let us know if there are UV blockers, as there are far to many variables that could cause that.
