Sliding Angle

[CleanIT]

"Sliding angle​

Talking about this concept is contrary to how coating brands frame hydrophobicity. Usually all they’ll mention is contact angle, implying that this metric is the sole determination of water repellency. But contact angle is only a static measure. A dynamic measure like sliding angle is what really tells you how easily a bead can leave your paint.

So what accounts for low sliding angle? There are several metrics at play, but at the most basic level the answer lies in the slickness of your paintwork. The more slick the surface, the more easily a bead can roll off."

I would imagine sliding angle would be as dependent on the size of the beading, as it is on the angle of the surface. This is coming from the owner of an FJ cruiser, which has no angles, other than vertical or horizontal.
