NeverWet Rustoleum Super Hydrophobic Coating Spray

Forum Sponsor
Watching some YouTube videos of this stuff, it looks like even body oils cause it to degrade.

I've got a feeling the original product was much more effective, but Rustoleum had to "water it down" to make it consumer-friendly.
 
DWR coatings are far from new. Nikwax, grangers, mcnett and many others have been making DWR for clothing for a long time. Dupont sells jugs of carpet DWR. Problem is, pressure and rubbing breaks down DWR made by those companies. It has to be reapplied.

By the sounds of it the rustoleum stuff is pretty much the same.

Good point, not to mention being absorbed through the skin

Assuming it's not toxic, this thing has unbelievable potential.

-I'm guessing every competitive aquatic vehicle owner in the US has or will soon be buying this for the underside of their boat/canoe/surfboard/etc..

A waxed boat/board will go slower than an unwaxed one. I am not sure how super-hydrophobic fits into this, but I would suspect it would be even worse than waxed.

"In extensive tank testing for world-class racing boats, it was established 40-some years ago that a glossy surface has substantially more drag than a matte one"
" if the water beads, like it will on a freshly waxed car, then the surface tension is high, and therefore its resistance going through the water is high."

The present DWR coutings are Hydrophobic, this stuff is Superhydrophobic. That means that (while applied) it should do a much better job of having liquids run off it. The real question (for us) will be how long it lasts in Motorcycle use.

I think that's just a marketing term, things are either hydrophobic or hydrophilic with degrees inbetween. The stuff is impressive, more hydrophobic than Teflon it looks like, but I have read before that it doesn't last and needs reapplying.

Water runs right off DWR coated products. Not sure what super repellency can do better. Shoot it back up in the sky? It would be a lot more impressive if they made super durable water repellent.
 
I actually just picked up a box of this stuff this weekend. Comes in 2 cans; 2 steps.
I spray 3 pairs of my shoes and used about half of the first can and 3/4 of the second. Second can calls for 2-3 coats.

So far, water repels off like crazy. Slightly decrease in breathability, not that bad with just walking around in them. Turned my brown leather boots bluish/grey then when dried, left a white crusty/powder layer. On my white shoes, it was completely fine.
Also applied it on my brown loose fabric slippers, no noticeable residue. Very water repellent.

The coating does come off if you rub it off and eventually, it will become less waterproof.


For those of you that say its similar to DWR or similar products... you are dead wrong!
The never wet coating repels on all angles of the water bead unlike the DWR coating with only repel at lower angles. http://www.neverwet.com/product-characteristics.php

water runs off, like it was never wet... <--- lol

Excuse the grammar and poor sentence structure... just ask me if you have any more questions.

I need science to explain this. There's a huge conflict in my head!
It's like when I was first introduced to counter-steering.
