A few close up shots of some EXO water beading...

My reflection in the beads...

Man that looks really cool, what kind of camera are you using to capture these shots?
 
I love it when the reflections make them look like full spheres. Great pics.:props:
 
Love seeing the metallic in the drops like a magnifying glass!:xyxthumbs:

Definitely, EXO has some of the most consistent beading I have seen to date. When they say the water contact angle is 110 degrees... every single bead has the exact same shape and contact angle

Great shots. I need to try some EXO.

Thank you, one of my favorite products

Thanks! I think I could capture more of that with some tripod shots and a tighter aperture.
 
Can someone explain "water contact angle". Looks like awesome beading. How old is the EXO? What do you use as a wash?

Pretty sure its the angle at which the edge of the water/bead forms with the paint. If you look in the last pic, you can kind of see a 110* angle where the bead is formed.

Very briefly...

Contact angle…θ…is a quantitative measure of "the wetting of a solid by a liquid".

Geometrically...
It is the angle formed by a liquid at the three phase boundary...
That is: Where a liquid, a gas, and a solid intersect.

If the contact angle (θ) is:

-More than (>) 90 degress...The liquid is said to be non-wetting.

-Less than (<) 90 degrees...The liquid is said to spread/wet well.

-A zero (0) contact angle...This represents complete wetting by the liquid.

Here's a picture I found that's illustrative of "wetting":

So instead of saying: "Look how well the water is beading"...

I'll suggest that it may be more proper to say: "Look how well the water is non-wetting


Of course if one does consider that CC paint has a
porous architecture (at least to some degree)...


Then the Washburn Method may be chosen for:
Contact angle measurement of a "wetting liquid".

This is some deep scientific stuff lol

Very true!!


Warning:

If that non-wetting liquid ('water beads') is not removed in a timely fashion...Then:

The depth of possible water-spots/water-etching
is an unknown variable to which one must contend .

Get them beads off of that vehicle...ASAP!!

Oh man if EXO only has a contact angle of 110 and it already has amazing properties as it is, imagine what it would be like when a legitimate super hydrophobic coating has been developed! (contact angle 150 or more, making it truly self cleaning) Can't wait, but it'd be questioanble if I'd use it as I have so much wash products and nubas...
 
Got it. High contact angle, small tight beads on hydrophobic surface.
