Japanese cars and clear coat failure #4485301

Why is it that I see so many Japanese cars (mainly Toyota and Honda, Nissan too) where the clear coat seems to be consistently failing. My moms 2007 corolla that was bought new began to have clearcoat failure roughly 5 years into ownership, granted it has been outside all of its life. But I see tons and tons of corollas, accords, Camry, tacomas, etc with bad clear coal out here in California and most of the cars are less than 10 years old.

This issue doesn't seem to plague American manufacturers as much.

What gives? Can this be prevented by consistent waxing?

Up here, we don't see that as often. I've actually been more impressed with the finishes I've seen from that era than previous to that. But, we get nowhere near the sun or heat of California. Sure, we see a few disasters, but not like it used to be, with various trucks losing paint down to the primer, not to mention the horrible rust.

Gotta give your cars a little love, man. Which car wouldn't just fade away with that ownership?

I've owned vehicles from Mitsubishi and Toyota. Never had any issues. There were rumors back in the 90's that Mitsubishi used thin paint coats. I still hear those rumors today on most Japanese brands. Besides a couple of rock chips, the exterior of my vehicles looked excellent.

I like to keep my cars clean and protected. There are so many good paint sealants and waxes out there along with coatings now that have UVA and UVB protection. I would always use a good coat of whatever you prefer. Check the labels for the uv protection.


Cannot see signatures any longer so it doesn’t matter.

Maybe the kid at the dealership applying the "$700.00 poly-wonder sealant" with a buffer and removing most of the clear coat at the same time.

YMMV

Love my Forester but the paint is thin and will feather scratch and swirl mark much too easily. Doesn't help that's a dark color.

The 05 Matrix has spent half of it's life outdoors. The color is silver but looks great. Prob since the finish is waxed regularly. Located in the rust belt as well but no visible rust. Darker colors seem to be a different story.

Worst failures I have seen were on certain Fords.

Exactly!

Here in South Florida, it's clear that just about brand suffers over time if parked outside during the day.

I work in the aviation world, we have some of the best paints available. None make it more than 6 years outside. Cars are no different. The degradation starts immediately. The bright sun is very powerful this far South.

In fact, my brand new Charcoal VW Jetta was in the shop for 5 or 6 weeks, awaiting parts. The clear coat had lost it's showroom new watery gloss over that time. Even the shop manager noticed it and offered to buff the car out. Which helped a good bit.

The addition of UV blockers and other additives helps immensely. But UV, heat and time take their toll.


People who count on their fingers should maintain a discreet silence.

Dunno what single stage paint means (and am too apathetic to try and find out) but my cars paint scheme definitely included primer because I can see there is still quite a lot of it left.

If there was any clear coat it was before my time.

My 07 has no issues so id assume its the sun. I am seeing a bit of bubbling paint on the lower rocker panels though. Thing is, around here not many cars on the road from before 07, so hard to say if domestics fare better. They might be rust free sitting in the scrap yard for other reasons..

Around here the bigger problem is rust, but we do see clear coat issues as well.

There are 3 Hondas in my family.

2011 Honda Fit - 70k
2003 Acura 3.2TL - 125k
2005 Honda Civic - 230k

All of them have some rust developing, the Civic almost has a hole in the rear fender. All cars are washed and waxed fairly regularly, and more in the winter. The Fit is garaged, the Acura came from Florida two years ago, and both have some small rust bubbles. I've talked to a few different paint shops and one said Japanese cars have weaker paint than German and American cars. He said there were different paint corrections he could only do on German/American vehicles. Not sure how true that is, since I'm not a paint guru.

I do find it interesting, because while the paint might be showing signs of rust on my family's Hondas, the undercarriage and everything else is very clean. I did brakes on a friend's mom's 2009 Ford Escape the other day. It has about 90k miles on it, and is hardly ever washed. The red paint is in fantastic shape, but the undercarriage and exhaust is completely crusty with rust.
