(Disclaimer: I had a fair share of sucker punches with self-cleaning surfaces..) Approaches towards self cleaning surfaces have been seen in the lab since a long, long time: They range from photocatalytic concepts (e.g. TiO2/SiO2/polymer hybrid coatings for house paint) to surfaces with a mixture of -OH/-CH3/-F (hydro-/lipophilic and mostly repellent) end groups that can be produces by plasma treatment, and many more…

What if this were an option at a carwash? I use full synthetic oil because it allows me to increase time between changes. I would pay more for a car wash that lasted longer as well. If the problem is a need to re-apply, can you get a coating that could be sprayed across the entire car without a need to mask out bits like in the video?

This is one of the reasons you should wax your car regularly. The wax helps water bead up and run off instead of sticking to the paint, and when it comes time for a car wash, what did stick comes off more easily. Once water stops beading up, it's time to wax it again.

This is another link bait situation from Wired, which seems to be happening often nowadays.

This is just some "stuff-resistant" paint that works better than the paint on cars now. It would be nice if all cars had this, but I'm sure that's just a matter of time / manufacturer.

I see this as an interesting business lesson for startups, but even more general. First, what a great marketing angle, a self-cleaning car, how cool is that! I imagine 6 o'clock news stations across the country showing clips from this video tonight. Second, what a great up-sell opportunity. Now every oil change service done by Nissan can include a new $50 charge (or whatever the market will bear) for re-applying the…

The cost of reapplying would be pretty high. Look at the amount of masking-off and prep work they do. You go in for an oil change and tire rotation which would normally take an hour but instead have to pick your car up the next day because it has to dry. I get a free car wash with each service of my car. That takes long enough.

That's why this is only offered on new cars, I imagine that Nissan would provide the dealers with some kind of mask template for each model of car they sell and the service mechanic throws this mask over top of the car, lines up the 4 corners and begins spraying. Heck, devising a quick way to put the mask on for a quick turnaround could even become a patent making this unprofitable for other dealers.

Regardless, my point was mostly acknowledging that even in mature industry's there seems to be room to innovate.

Blogspam for https://www.youtube.com/watch?v=UwoGsCAKsxU

Yes. We changed the url from [1]. Wired is one of those sites that produces some solid articles and a lot of spammy fluff. We're not ready to lightweight it [2], but we're close.

Very interesting, I wonder the environment hazards, if any, of such technology.

It would seem like a great candidate for a free spray-on update at your neighborhood dealership... the same kind of loss leader for maintenance that oil changes are.

Look at that headlight on the treated side of the car. The cloudiness these types of applications add makes it look like the headlight of a decade old car.

But they masked the headlights in the treatment process. Which also raises the issue, you'll still need to wash your headlights and number plate.

I don't think they did for the vehicle they took the picture of at the top of the Wired article. There's a clear difference between the clarity of the headlights.

That's great until it breaks down (and it does). You can't get a basic detail, since the supporting products also won't work with it.

Once it does start breaking down, you have issues getting basic stuff like soap bubbles to work as needed to help clean the spots that are broken down.

If it can't be layered, without adverse effects to the color of the paint, trouble.

If it can't be removed for repainting, etc. trouble.

Probably usable for some cases, but not going to get traction in the broader market until someone can fix long-term cost of ownership issues.

Have some car zen. Watch Ammo NYC videos on youtube https://www.youtube.com/user/AMMONYCdotcom
