I've had the worst Luck with this 2015 SRX. The Warranty has just run out on the 22nd of Feb. 2019.
Now, while I was Waxing my car's Front End I noticed RUST coming through the Paint near the Chrome on the Hood's Front, from the inside out. It's just a speck now, no bigger than 1/8 th of an inch in Dia. but nevertheless it's Rust.
I haven't called Cadillac yet as I don't know what Fine Line difference is between Corrosion and Rust Though.
Corrosion is 4 Yrs and Rust Through is 6 Yrs. coverage. I guess the Real word here is Through.
Rusting is the common term for corrosion.

I believe the hood is aluminum, had the same issue on a 2010, removed the plastic chrome piece and it was beginning to bubble around all the holes.
Stop by a dealer for them to inspect it, hopefully it'll be taken care of.

The hood is aluminum and the fenders are steel?

Correct, it's a weight savings effort. Check it out using a magnet (cover it with something to prevent scratching the hood)
Some other brands of vehicles have had corrosion issues because of the lack of a grounding strap from the hood to the body and the fact that improper paint prep has caused corrosion.

I see.. I took a look at the info you linked. I was wondering if you possibly knew the answer to a question I’ve always been curious about. I’ve noticed on some vehicles [Cadillacs included] that the paint they use on the hood seems to be visibly different than the paint used on the other body panels i.e. the paint on the fender will be much sharper and have mirror like reflections whereas the hood will be a bit dull in comparison. I’ve seen this mostly on silver/gray colored vehicles. Are you familiar with that? If so, do you know why they do it?

 

[GEORGEC]

What age vehicles are you seeing? The most likely cause is that the hoods take a lot more of the suns rays than do the fenders. Thereby the paint on the hood deteriorates much faster.

The hood, does in fact, oxidize faster than the fenders and sides, as does the top. But you've got to stand on a ladder to see the top, plus most of them have that big ole sunroof.

My brother bought a 2004 CTS brand new and the paint was like that from day 1. It’s not a matter of deterioration, it has to do with the way they paint the hood vs. the rest of the panels.

Even on my 2002 bronzemist DTS you can see how the paint on the rear quarterpanel shines like a mirror whereas the paint on the trunk just doesn’t quite shine the same way. It’s because they used totally different paint on the horizontal panels vs. the vertical panels of the car.

No amount of polishing will make the hood or trunk shine like the sides of the car. The paint is different, my question is why do they use different paint?

My body shop manager says that simply is not true! The whole car is painted on a "spit" at the same time! The only items that are paited separately are the bumpers, because "flex agent" is added to the paint on the bumpers and they may look different from the rest of the painted surfaces over time. There is no different paint or proceedure for painting the hood, from the factory or any other time, unless it is a different color, ie blacked out,etc.

Your body shop manager where?

I know for a fact there was a difference in the paint on the hood to the rest of the car on my brothers silver CTS.

 

[ELDORADO2K]

My brother sold that car... But I’m going to find another 1 and take pictures.

And you can see the difference in the paint on my trunk compared to the quarter panels. My car has not been re painted.

I’ve seen these characteristics on several car makes and it’s always on silver tone paint. I don’t know why but I’ve always wanted to know the reason.

 

[WILLY92]

Your body shop manager where?

Those are older cars, Bud, and will have oxidized hoods, tops and trunks.

Bodyshop Manage, here, at our dealer, where I work.

ANY CAR that is not garage kept and is 5+ years old will start to show that on the hood, roof and sides. It is called oxidation and is most apparent on thoses surfaces, BECAUSE they face the sun ALL THE TIME! This why I keep my 2014 SS(a car that I care about) garaged, and my wifes SRX(not so much) sits outside. And it just so happens that the hood, the front part of the top and the tailgate are all a little dull compared to the sides because the previous owner did not keep the car in the garage.

 

[GEORGEC]

Let me see if I understand. You have had one problem with the '15 and you think that qualifies for "worst luck." ?????

George

 

[GEORGEC]

Please provide us with the source of this "fact" that there is different paint.

All I need to do is locate a 2004 Silver CTS. If you happen to run into 1 on your own [there’s plenty around] take a good look at the hood next to the fenders in direct sun. It’s not due to oxidation, there’s just no way...

Btw I know a thing or 2 about oxidation and paint in general when I see it. I polish cars for a living.

Here’s a pic of the hood on my DTS how I bought it a few months ago.

Here’s how it looks now after I was done polishing it back to life.

It made great improvement, but it’s still not quite on par with how good the fenders, doors and quarter panels turned out but I’m by no means disappointed with the paint on my car.
I used a paint depth meter to confirm it’s the original paint all around the car.

I’ll be on the lookout for a 1st gen silver CTS. Good day my friend.

 

[ELDORADO2K]

Just for the record: I never declared that different paint was the definitive reason to all this. My 1st question has always had to do with the hood being made of aluminum in comparison to the fenders, doors, which are made of steel. I’ve always pointed to that as a possible reason for the visual difference in the paint, however I’ve never known whether that plays a real factor or not, but I’ve always figured maybe that could be the reason? Does the factory paint bond the same way to the steel panels vs. aluminum? I dunno.

I understand you've stated the vehicles have original factory paint but check this out: http://etalon.gr/blog/2014/04/15/pa...ingclouding-prevention-is-better-than-remedy/

Also around the same timeframe, EPA mandated changes in painting procedures that caused auto manufacturers to change formulas to a water based paint. There were a few Cadillac colors that were recalled due to improper bonding to the primer.
I don't know if in fact aluminum panels had anything to do with all of this but there are many auto manufacturers that have had customers unhappy how their vehicles look, not specific to any one brand.
Environment does impact the top more than the sides as does ultraviolet light.
Not an expert just offering some ideas.

Those cars are still 10+ years old, you can't fight the sun beating down harder on the hood rather than the fenders.

My brother bought his car when it was just 2yrs. old. from the Cadillac dealership. The car was maintained about as good as anyone could ever ask for. The paint was always cared for and protected with synthetic sealant. Never saw snow.

From a few feet you couldn’t see the difference, but once you got up close especially if pointing a bright paint inspection light onto it you could see the difference and it even had a different texture to panel/paint. The fenders had a squeaky clean look and feel whereas the hood, while the paint had texture was smoother to the touch, not squeaky clean. That’s the best way I can describe it.

I found this picture of the hood. Unfortunately it’s not in direct light, but you can tell it lacks the same depth of reflection that the fenders have. [you can bearly see the outline of the trees in the reflection]

I took this picture of the hood on my Seville immediately after taking the picture of the CTS. Both in the rain, but you can tell the paint on this hood reflects much sharper compared to the CTS. [look at the trees in the reflection. Near perfect even with all the rain]

Compare it to the trunk of the same CTS. The trunks paint was far superior to what was on the hood. The hood never reflected like this.

The hood reflected more like the front bumper. Exactly like the bumper.

 

[WILLY92]

All of that is well and good, and, by the way, the appearance of that headlamp tells the story about how much sun that car has recieved, but anyway, when you find someone(credible) who can tell us that the hood, roof and trunk lids are painted with different from the rest of the car, let us know.
