Re: the end of Bottom Paint as we know it...

From the application instructions page:
he surface will lose it properties if treated with detergents, soap, some solvents or high pressure
water. Due to the natural oils in the skin, excessive handling
with bare hands of treated materials can cause a reduction in
performance as can severe abrasion.

It would be great if it held up under sailing conditions, but I'm not so sure.

Re: the end of Bottom Paint as we know it...

Can you use Ultra-Ever Dry where it is continuously submerged in water or liquid, like the inside of a pipe with constantly flowing liquid??

No, this is not a good application. The reason is the nano-coating relies on a barrier of oxygen/air to form the barrier on the surface of the material it is coating. Unless the coating can become exposed to air every now and then, it cannot “recharge”.

Re: the end of Bottom Paint as we know it...

Yeah I saw this, it's pretty incredible.

However, if you go to their website and read the FAQ:

How long will Ultra-Ever Dry coating last? Answer: The SE 7.6.110 formula’s longevity in use is susceptible to environmental conditions (UV / abrasion). This coating will generally last 2-8 months in direct sunlight and outdoor conditions before recoating of the top coat would be required.


3. Can I spray this on the bottom of my boat? Answer: We are still testing this application. We do not have any meaningful or conclusive results at this time.

I don't fancy hauling out every 2 months...


If it is *really* superhydrophobic, would my boat fly?

Re: the end of Bottom Paint as we know it...

This is a report, somewhat unscientific yet instructive: The Internet-demanded, partially scientific testing of Ultra-Ever Dry (in HD!) | Ars Technica

In short, here are some quotes:
However, our sacrificial toilet from the hardware store fared excellently when coated with the stuff. The difference between the treated and untreated portion of the bowl when pelted with water and poo wet potting soil is obvious. That being said, Ultra-Ever Dry is "air powered"—its ability to repel water and oil depends on being able to trap a thin layer of air. While Ultra-Ever Dry's documentation shows that the coating when properly applied will remain water-repellant at a depth of one foot for "months," you might need to periodically drain a toilet with Ultra-Ever Dry applied to the bowl (depending on the way water swirls around your toilet when you flush it) in order to let it "recharge."
Also, I'm not sure I'd set my nether regions near the stuff, as exposure can cause skin irritation.

The other possible side effect of coating your driveway is contaminated run-off. The coating job I did resulted in no small amount of excess Ultra-Ever Dry being carried off by water or rubbed off by my fingers the first time each treated object was handled (you can see a thin film of Ultra-Ever Dry back in the first video in the water collecting at the bottom of the toilet, for example). Some amount of Ultra-Ever Dry will almost certainly be carried off of your treated driveway and into your yard and your storm sewer, and I don't know what the potential consequences of that might be.

A week after filming this, I re-tested the treated section of the driveway and found that exhibited absolutely no superhydrophobic properties at all—it had reverted back to regular driveway. The Ultra-Ever Dry site does make mention that the product is somewhat susceptible to UV exposure, but my application method is more likely to blame than anything else. If you plan on applying Ultra-Ever Dry to your sidewalk or walkway, you must be meticulous with the application. Hand sprayers are simply not going to cut it.

Re: the end of Bottom Paint as we know it...

It would be an interesting test to see it applied to one of two matched day racers.

Re: the end of Bottom Paint as we know it...

My experience has been that folks who do not make their living manufacturing anti fouling coatings and have no real understanding of boats and the fouling conditions they live in are unlikely to produce a worthwhile anti fouling product.

fstbttms is not going to hold his breath, but the rest of us out there will be very interested in the many boats that get this treatment and their reports.

You know something the rest of us don't? What "many boats" are you referring to? What "treatment"? You understand that we're discussing a theoretical anti fouling coating that doesn't yet exist, right?
