Here's what I did:
- I took a scrap of fiber-reinforced ABS plastic (left over from the refrigerator refurbishment) and masked off one side of it. The other side got the NeverWet treatment. I suspended it (from the hole you can see, partially covered with blue tape) in the water off our finger pier at Anacortes on December 21, 2014. The finger pier is a floating one, so the coupon will never be exposed to air, except when I lift it up for inspection.
Report on Experiment #1
|Experiment #1, as of Dec 2014|
Report on Experiment #2Experiment #2 began in April of 2014, when I applied NeverWet to our dinghy propeller. It was amazing to see that the submerged prop looked like it was made of polished silver due to the thin layer of air it retained while submerged.
We used the dinghy normally for the entire 2014 season, giving no further thought or special attention to the prop.
By the end of the season, the nano-tech coating had ablated off the outer 1/2 of the propeller blades, but was still active on the inner half.
From this I conclude that NeverWet is not suitable as an anti-barnacle coating for boat props (guess we're still stuck with Barnacle Ban), but it could likely serve well on things that do not suffer from the abrasion of high-speed turbulent water contact.
