I am looking for MAXIMUM protection from the sun for certain applications. Mainly, for cars that live outside (no garage, carport, or cover) what types of products are best to keep the clear coat protected from the sun? I know there are benefits from coatings, especially that they last longer once applied but setting that aside what types of product(s) will offer better protection from the sun??

Just to give an example I have been using Klasse AIO + Klasse Sealant (+ wax sometimes on top) but I am wondering how does this package protect from sun VS say Cquartz, Opticoat, etc??

Also, when using the Klasse AIO and Sealant which of the two offers better protection from the sun the AIO or the Sealant???

Is there some other type of product that offers the best UV protection???

Thanks!!!

LSP, whether it be waxes, sealants, or coatings; they are not like sunscreen with SPF ratings. I don't think anyone can say what is "best" or has the maximum amount of UV or any other kind of protection. Any evidence presented would be mostly anecdotal. Your best bet would be to use what you like, and use it relatively often so you know that your vehicle's paint is never unprotected.

FWIW, my Honda Element lives outside. I coated with CQUK last February, and I gave it a Reload last week. Works for me.
 
Optimum and CarPro coats advertises that theirs have UV inhibitors, try to look at those.
 
Thanks very much for the replies trekkeruss & hdez. I will look closer at the coatings because if I can get uv protection and long lasting that would be perfect. I was actually thinking about trying CQUK + Reload so thanks for the tips.
 
Gloss Coat is one of the easiest coatings to apply and is user friendly. A good place to start.

Pinnacle Black Label V2 is also user friendly. Offers UV protection according the description on AGO's store. There is a sale on Pinnacle coming in a few weeks.
 
I know at least 1 of the Duragloss sealants advertises as containing UV protection. I recently applied 111 and it's insanely glossy. I think that's the one with UV protection.
 
Optimum Car Wax is the best I have found and I use it once a Month or so. Just like sun screen for your body it needs to be replenished. Optimum states 5 Months but I would not trust that in high UV areas. I have been on this UV blocking for quite a while living in AZ. A lot of products state UV protection but do not state for how long, OCW states UVA and UVB and is easily applied.

Yeah, the funny thing is that there was a discussion about this on the OPT forum recently, and they said that the coatings have inhibitors and give better UV protection than OCW.

The only real experience with a coating I have is with Dlux. I used it on the Black trim at the door pillars and rear step of the Van trying to alleviate the oxidation problem. It still oxidized under the Dlux which I had to remove with compound (that was fun) so I could polish out the oxidation. That was the last coating I used. I am not denying any claims to what may work as I do not know of any real world tests and documentation of any products that claim UV protection. The best protection is to park in the garage and only drive at night :laughing:

I don't know if you were involved in that thread with the owner of GTechniq (Rob?) who was talking about if you put C4 on too thick it will haze up after a while (possibly months). It's kind of like getting a high spot with a paint coating. I'm sure the same thing could happen with DLux. I personally was pretty disappointed with C4, although I will take Rob at his word, because later I used it on another piece of trim and it's been fine (although we know that all trim is different). Anyway, it could be that's what happened with your DLux...I'm still waiting for the C4 to wear off, it's only been like 5 years.
 
If it's a coating wax or sealant, as long as you maintain your paint you should have no promblems.If you work a lot and can't tender then a coating would be beneficial.

Yeah, maybe. As tough as it was to get off I did not want to do that again. Being 5 years with C4 I take it as being a good thing unless you wanted to try other products.

5 years of the cowling looking all faded is not a good thing, but it's all ribbed and I just heard about this "too thick" application a few months ago. I put some WETS on it periodically. Since it (supposedly) looks faded when there is too much C4 on, and it was faded before, I don't know how I would tell if I had scrubbed it off. I know putting more (C4) on top didn't re-darken it. Anyway, I'm just babbling.

And here I assumed the C4 was looking good and lasting a long time. The lasting a long time may be true, the oxidized cowl doesn't. That is exactly why I will not put a coating on, when things go bad it is really bad with coatings especially on something like a cowl panel. My bad experience was on flat panels so it came off with enough compounding.

The thing that will provide with the best UV protection is parking your car in a garage or a carport. Buying a light colored car may also help maintain paint, as the do not reach the same high temps as darker color cars do - although it has nothing to do UV.

Another point is, while UV rays may damage all paint - the fading that happens is likely
Much less noticeable on lighter color cars - mainly white and silver. This is not related to clear coat failure, but actual fading of the color of the color coat that happens after years of being in strong sun.

For whatever reason, red cars are also highly susceptible to damage from the sun. Red is the quickest color to fade or oxidize IME.

As for what product prevents it - there is no magic products and no double blind random testing. So, all we are left with are manufacturers' claims.
