Silicon on car windows

As you've probably discovered, once you start using RainX, you have to keep using it, at least until the time you next change your wiper blades, as a residual amount of it gives a streaky windscreen

This product used to be used on would you believe, Hovercraft pilots windows. I remember the name and of course those which went over the sea constantly needed cleaning due to the build up of salt. I never saw such fast wipers as they used to use! I'd have thought it might be available in industrial quantities though,quite how much you would need to buy to get a reduction, I have no idea!

Ships bridges often have rotating inserts in their windows, which throw the water off, rather than wiping it away.

Kent screens:

That's it. I once borrowed a motorcycle helmet with a visor that worked on the same principle, except that it was operated by the airstream, via vanes on the side. The faster you went, the faster it spun. It was remarkable effective.

Isn't ramming other ships a navy tradition?

Left hand down a bit :-)

Oh what a lark!

Is that a euphemism?

George Melly had his own way of putting it.

No, literally. British and other warships were still fitted with rams right up to end of the 19th century, although the Royal Navy only managed to sink one of their own battleships, following a collision during manoeuvres, and a passenger liner, which collided with the ram bow of an anchored warship. Ramming was, however, used to attack surfaced submarines in both world wars.

I once saw motorcycle helmet visors that worked the same way, driven by wind speed.

Silicon, or silicone?

If you ever see my new van I'll show you the massive amount of silicone that some arse used to try to stick a dashcam to the windscreen.

Its silicone in fact but a brand name changes it a little. After my remark about Hovercraft windows, I immediately thought of. My Hovercraft is full of eels. for some odd reason. Brian
