Over time, windscreens and windows become pitted, scratched and etched thus greatly reducing their ability to repel water. Wolf’s window sealant makes old and new windows and windscreens bead water like never before, which will greatly improve vision when driving in the rain and can eliminate the need for using windshield wipers.


Thoroughly clean the surface to be treated and clay or polish with Shine & Seal nano polish if necessary to remove any imbedded contaminants. Apply a moderate amount of sealant to an applicator pad or a microfiber towel and firmly work into the glass in small sections. Once the entire glass has been covered, repeat the application until a solid haze can be seen over the entire area. Let stand for 10-15 minutes and remove with a clean, damp microfiber towel or with window cleaner.

Wolf’s Glass Guard nano coating will form a form a super-hydrophobic, self-cleaning shield on glass surfaces. This product is especially useful on windscreens and other glass surfaces where clear vision is paramount. This coating forms a layer of protection that is approximately one molecule thick (1 nanometer = 1– 9 meter = 10– 6 micrometers), as the average size of an atom is 0.2 – 0.5 nanometers thick.

A single nano treatment consists of 3 layers: The first or “bonding layer”, forms the foundation of the coating by becoming part of the substrate itself. Being that this layer actually becomes a permanent part of the surface it’s being applied to, this SiO2 or “quartz/glass” layer will protect from the elements for an exceptionally long period of time.

The second “filler layer” anchors to the “bonding layer” and fills the gaps between nano particles to form a homogenous nano surface, which is necessary for the for the last layer to form properly.

The third “hydrophobic layer” bonds to the previously formed layer and provides the surface roughness which creates the hydrophobic lotus effect.

Properties of a  super-hydrophobic (nano) coating:

  1. The coating itself is very thin, circa 1 nanometer thick, which can not be seen by the naked eye
  2. The coating forms a very strong bond to the surface and the “bonding layer” is quite difficult to remove
  3. The coating does not “layer”, meaning that adding several layers will not “build” or make a thicker coating. In other words, it will not adhere to itself.
  4. The coating will repel water and dirt/contamination will not form a strong bond to the treated surface.

In cold weather, the hydrophobicity of nano coatings may decrease! In these conditions, the moisture in the air tends to form a dense layer of moisture on the surface which can “stick” to the surface and prevent water drops from forming because of the constant moisture in the air. For example like on a windscreen when temperatures are low, the wiper blades will clear the screen, but another layer forms very quickly and the wipers are needed once again. Once the inside of the vehicle is warm and the windscreen itself also warms up, the hydrophobic properties of the nano coating will reappear. This is why we use warm air when we defrost a windscreen :)!
