This stuff is just amazing! I can think of any number of different uses for it. Have a look at this video – I think you’ll be impressed:
Apparently it’s a superhydrophobic material – which is a clever way of saying that it is really hard to get anything coated in it wet.
It’s also oleophobic – which is a clever way of saying that it doesn’t like oil any more than it like water.
It is actually available commercially. It’s intended for use by professionals only apparently – and you have to be careful how you handle it and how you apply it. It’s also fairly expensive, which is fair enough I suppose for something that has so many potential uses.
Keeping water off things is a good way to keep them clean (and dry of course), but it will also give you other benefits. Stopping things getting wet and damp will prevent, or significantly slow, the growth of mold and fungus.
It’s also a good solution for any item that you don’t want to get iced up in the winter time. No water = no ice. Simple.
Apart from the cost, the other downsides are that you will need to take care when you apply it and use properly certified breathing apparatus and personal protective equipment (PPE). It also has a relatively short life in use and will, depending on the amount of abrasion in the environment you use it in, require to be reapplied on a regular basis.
Even so, it’s a product which, in the right application, looks to have a great deal of potential.
