Nano experiment

I'm excited to try this nano stuff.  

For the experiment, I chose the subject to be our fabric sea hood.  (Yeah, I know what you're gonna say.  Building a real, solid sea hood is on the agenda.  But that's why this is such a good candidate for the test.)

When the hatch is closed, there is no support for the fabric so it collapses into a shallow depression that holds water. And because the hatch is closed, and its wet all winter, mildew runs rampant on it. Opening and closing the hatch, which will also go on all winter, will give it some good mechanical exercise too. 

Applying NeverWet is a two-step process.  Following the directions, I applied Part One and waited 30 minutes for it to dry.  Part One was completely clear.  It smelled suspiciously like an acrylic enamel going on, and it stiffened the fabric - just like an acrylic enamel would.  At this point I was really happy that I had chosen a part of the dodger that is scheduled for removal as the experimental subject.

After 30 minutes, I applied Part Two.  This is an entirely different composition, and apparently uses an alcohol as the solvent.  As advertised, it left the fabric with a white, frosted appearance.  Once again, I was glad for the choice of experimental subject.

It will be many months before this test can be declared a success or a failure.  But the results the next morning, were pretty amazing.  The dew was scattered over the surface like a field of diamonds, and a few fat drops had consolidated and swept up their near-microscopic brethren, leaving dry trails behind them. 


  • Really, really hydrophobic coating!


  • $18.75 for coating to cover 10 ft2.  That's $1.88/ft2
  • Substantially stiffens the fabric
  • Leaves a white, frosted appearance on the fabric (might be OK for white fabric)

Addendum:  After Rain

If you look closely, you'll see actual air, under the water
