Testing Slickness of a Hard Surface
I was wondering if anyone could recommend a testing device and/or procedure for slickness of a hard surface. We are trying to determine how ‘slick’ a car surface is after it’s been treated with our product. Any suggestions?

I am not exactly sure what you mean by “slick”
If you are referring to gloss and shine there are gloss meters that can be used to measure this.
https://en.wikipedia.org/wiki/GlossmeterIf you are referring to if a surface is slippery you could possibly look at using a tribometer (used in determining coefficient of friction for floor surfaces) or similar.

Perhaps you could puff a fine mist of water droplets from a fixed distance and use a travelling microscope to calculate droplet diameter and droplets/sq cm and then pay an expert in such things to use his arcane knowledge of obscure math formulae and advanced physics to formulate an equation that describes the performance of slickness. Then measure your product against it. Maybe PTFE could be at one end of the scale and the other? Well, paper for instance.

Maybe pull a spring loaded rubber probe along the surface using some kind of posh spring balance.

Wow. I am impressed after seeing those links.

Could you be a bit more precise?

Are you able to coat both sides of a flat metal surface with your coating? If so, you could rig a relative (suitable for comparisons) static friction measuring device with a C clamp, 2 durable pads, a spring gauge or a pan + weights, and string.
