Not much Hydrophobic protection from that wax...the beads of water are very flat. You should try the Nanoskin Hydrophobic wax..its beads very comparable to the pic below and its very slick.

Here is a better one....but this is with the Nanoskin Shield sealant.

Wow, very nice picture of the beading.

Thank you...that product is totally amazing. Nothing is bonding to the sealant...not even contaminates, bird poop and its been raining hard for the last few days...the rain just runs off and its not even leaving water spots..its still 18 yr old stipper butt smooth.

What exactly is hydrophobic protection.
 
BlackFire is one of those lines taking the detailing scene by storm and their spray wax is no exception. :bigups

A full line of quality products and reasonably priced....:bigups

I am very familiar with hydrophobic properties. In fact here is an answer I have written that explains water beading on a different forum.

Let me confuse this even more my friend...

Surface Tension affects liquids, not the actual surface the liquid is on... But external factors, such as the air and surface will effect the surface tension behavior of the liquid.

So when we say a wax gives more surface tension, this wouldn't mean that the surface the wax is applied to actually has more tension, but rather the liquid applied over the surface will have more tension do to the interface of the two together.

If we want to get really technical, surface tension only refers to liquids and it measures how strongly the liquids are attracted to each other.

Water beading...

Water has a high surface tension, that is water is attracted to itself. When we look at water beading, the water, which is pulling itself inwards (like gravity that holds a planet together) is interacting with two different mediums, the surface it is applied to and air. Where these different mediums meet, they form a contact angle. This is because the different forces (the air-to-water, the water-to-water, and the surface-to-water) must balance. As a result forms in little droplets.

The less attracted water is to the surface it is applied to, the stronger it will bead. This isn't due to a change in the surface tension of the water itself, but rather a change in the water natural attraction to the surface.

Does higher or lower surface tension cause water beading....

Technically neither. While chemicals can be added to the water to increase the surface tension or decrease it (increasing its pull to itself or decreasing it) the result of water beading has to do with nature balancing the water's attraction to itself with compared to its attraction with surrounding objects.

A surface that promotes small, tight, almost spherical water beads MIMICS an increase in surface tension, but it really isn't changing water's attraction to itself. Instead it is decreasing its attraction to water.


My question is how exactly would you correlate hydrophobic (water beading) with protection.

Water repellency and contact angle is certainly impressive and offers a lot of benefits (both visual and physical) but I'm not sure that protection (protection from what?) is one of them.

Yes...I didnt realize I had to explain that term...lol

You said Hydrophobic Protection and I am trying to understand what you meant by this.

Are you saying that product that has a great contact angle produces better protection and what, exactly, type of protection your referencing?
 
Does water more water beading mean better protection?

I don't have the the knowledge Todd or others here have but my gut tells me beading isn't the only way to gauge protection. For instance some products have sheeting qualities more than beading qualities. I know some prefer sheeting over heading because they feel it will reduce the risk water spots and etching and the surface dries.
