Highest level of UV protection from an LSP?

I've been thinking about UV protection and how it applies to detailing and detailing products. It seems like most every LSP says it protects against UV, but I've never seen any test comparing LSPs in this regard.



Where I'm going with this... The interior of a car gets it's UV rays entirely through the window glass (unless you keep the windows or convertible top down). There are a variety of products made to absorb the rays at the surface of the interior (303, etc.), but it should be just as beneficial to block the rays at the glass instead. This is also much easier than trying to coat the interior with protectant (and on top of that, I really don't like the look of most protectants).



The good thing about glass is that you can use just about any product on it and it will look the same. So now I'm back to the question of what would provide the best UV protection. I'm thinking good options might be Zaino, DG, Werkstat, Collinite because they'd all be very durable and they all claim UV protection.
 
I don't care too much about UV protection with modern clearcoated paint. The protection in that will far surpass any coating or sealant that goes over it.
 
Well, like you said, they all "claim" UV protection. Which one is best at this? Who knows, impossible to be dogmatic about 1 product versus others. I like your options tho, thats where I would start...PS..Zaino seems to market UV protection more so than other companies, for what thats worth. Zainio "claims" there Ultra Guard UV 40 is top stuff.

I thought the most common cause of clear coat failure was UV damage due to the owner not waxing/sealing their often enough? The next most common cause I thought was due to thinning the clear due to over compounding/wet sanding.



Please don't take this as arguing, just curious.
 
To get back to the OP topic, I beleive the poster was referring to putting something on his windows and windshield to block the UV rays from hitting the dash and other areas.

Yes, reducing the thickness of the clear *can* cause premature failure. When's the last time you saw a 5 year old car with flaking clear? You'll most likely see it occur on painted trim(bumpers/moldings/mirrors) due to the fact that many are single stage & lack the protective clear(w UV blockers). I've see 1000's of late model cars down here that aren't sealed and can't remember the last one that had clear failure from sun exposure. IMHO, I'd be way more concerned with acid rain eating through your finish causing failure.

That's correct. Thanks.
 
At the 5 year mark my CC Laser Red Mustang had faded paint on the spoiler and bumper covers. Clear coat paint won't protect from all fading.
 
They have UV protectant window tints. They don't even have to be dark, but they absorb UV rays and heat I believe, I would go that route if you really wanted UV protection as I don't think waxing your windows is going to do very much as far as UV protection.

Are the bumpers and spoilers on Mustangs clear coated? For some reason I am thinking they are single staged.

Actually, they are clearcoated. I believe that red is most prone to UV damage. My car was repainted at the 1 year mark and had a special PPG clearcoat put on that wasn't availbable from the factory-and it still faded.
 
You'd figure that colors that are more attractive to heat/sun would create more damage quicker. Red's kinda in the middle of the spectrum right?
 
red is always seen to oxidize and fade faster IME. I've had 3 red cars from 3 different car makers, and each of them faded. I won't ever buy a red car again.

Not too long ago, David quoted a guy in the automotive paint industry... one of the very "in the know" kinda guys, and if I remember right, he stated that UV protection in an LSP is *completely* worthless on a clear coated paint, and was nothing more than marketing hoopla.



But of course I can't find that post now...
 
As far as the paint, I actually thought I had started a thread about this years ago but I can't find it, it must have been in someone else's thread. I postulated as to whether the reason that the flexible parts oxidize faster is because of the different paint or because the surfaces get hotter in the sun because they are plastic and have lower thermal conductivity than metal parts. My old car had plastic side mirror housings and deck lid spoiler and the clear on those parts failed years and years before I got rid of the car (had it for 16 years). I had damaged one of the mirrors and had it repainted when the car was less than a year old, that one lasted much longer than the factory painted mirror, the spoiler lasted longer than the factory painted mirror but not as long as the repainted mirror.

I believe you may be thinking of this topic: http://www.autopia.org/forum/car-de.../49922-asking-davidb-elaborate-longevity.html , or maybe not :nixweiss:
 
Setec, it was a similar thread (discussing UV damage), but that wasn't the one. The one I'm thinking of was a multiple subject thread: CC thickness, UV protection of CC's, UV protection of LSP's. I *think* it was David Fermani who quoted the source stating UV protection in LSP's was worthless... I could be wrong, though. According to my wife, there's a *very* good chance of that...
