Every year? C'mon subs, we're not all car enthusiasts.

I went so long between washings on my CJ 5 that when I DID finally wash it, the mud had stained it.It forwver had a faint orange-brown tinti to the areas of the paint that had mud on them.

Does this mean that bird poop will just slide off too?

Not, but since it repels water, you won't be able to wash the poop off, either.

God, what if that was a real consequence and nobody thought to check it before the big ad campaign rollout?

I tend to wash mine when the accumulated crud is causing drag.

I apply the same rule to my car.

Car washing baffles me. Don't get me wrong, if you like a clean car, have at it. But I think of myself as a reasonably clean person--my house is fairly tidy, I shower every day, and all that--and even if my car somehow got caked in mud from top to bottom, I can't really say I'd care enough to do anything about it. It's gonna rain eventually.

A car that gets washed in the rain? Does it drive itself, too?

My childhood dreams have almost come true! The future is now!

I am against washing my car for religious reasons.  That doesn't make me hydrophobic.
 
2014-05-19 12:03:05 PM
They're not hydrophobes, they just don't like it when water is waving its wetness in their faces.

In my experience, birds only aim for the windows. It's like there's an invisible bulls eye on the drivers side windshield.

My wife brought back a new plunger a few weeks back that was supposed to be hydrophobic. I rolled my eyes and laughed.

Until I used the damn thing. Honestly it's amazing watching water not stick to something.

a hydrophobic car?

No thanks.

I want a car that's rapid, not rabid.

Yeah, this.  As the owner of a black car I can honestly say it's not worth trying to keep the exterior clean.  The damn thing looks dirty after about 5 minutes of driving.

I wonder what happens when someone tries to wax it, or goes through a car wash that applies "wax". Is that stuff repelled, too? Does it flake off and look like a bad sunburn for a while? Does it ruin the hydrophobic coating?

And how long does the treatment last?

Actually hydrophobic coatings are also insanely useful for tings like air conditioners and thermal vents, etc.

IF you can keep water droplets from forming, you can keep them from sticking/freezing, greatly improving the efficiency of the air conditioner, heat pump, etc etc.

/But yeah hydrophobic surfaces are NEAT.
//Have to make them for one of my nanosphere deposition processes...

Well, I'm not sure if you'd *need* to wax it? I mean, the entire point of the waxing treatment is it's sort of a 'cheap' hydrophobic coating/a sealant to keep the water out.

Jeeps are NEVER supposed to be washed.  It voids the warrenty!

Cool. I took my car in for its 60k tuneup last week...which turned out to be just an oil change. "These newer cars don't need as much maintenance," the service writer told me. My last car, the 60k tuneup involved 75 different things and cost me $500.

Science! It works, biatches.

Yeah, but people will do it anyway, even when told not to. Kinda like how my ex-wife insisted on using metal implements (including serrated steak knives) on our non-stick cookware for 19 years.

Just the visible parts shouldn't be washed, the undercarriage should be sprinkled after each mud puddle, a good oscillating sprinkler works well. Easier to work on a clean engine bay. And with Jeeps (Just Empty Every Pocket) you know you will need to work on it often.

That's because you wash the darn thing!

No, that's why I drive a Landcruiser. :)
