Bence said:Such spectacular contact angles, aka superhydrophobic water behavior works in nature on microscopically rough surfaces (see Lotus leaves).
Super- or ultrahydrophobic coatings work nicely on totally flat surfaces too, but their durability is too short to make them useful for automotive applications.
+1.
Apollo_Auto said:IOW, it's beading like that on a "bumpy" surface!
Superhydrophobic surfaces like Bence mentioned are because of bumpy surfaces. I refer you to this lotus leaf image
It might be more impressive if your surface beaded as well as exhibited shine/gloss. You might as well just covered your hood in shortening.
