Anti fog rain solution

[Apsin]

Can someone suggest anti rain and fog solution for helmet visor?

The only one that actually works for a prolonged period in very poor conditions is an electrically heated snowmobile visor. Unfortunately, they aren't road legal in the UK.

There are various other solutions which are better than nothing but they all deliver less than they promise.

I have a pinlock in my Shoei that I use for commuting, I also use Nikwax Visor Proof, and I also have this weird french made potion called Visio Dry that is supposed to completely deflect all water from the treated surface.

The Nikwax is really good, the Visio dry stuff doesn't work that well as it wipes off too easily. I'm sure it does what it says on the tin, but it's not right for the outside of a bike visor because you generally want to wipe away moisture and so on with a Vee wipe or similar. It seems to work for 5-10 minutes and then... stops.

The Nikwax is reasonably priced for what it is, and so with my extensive trial and error experience, I'd recommend a pinlock and the Nikwax solution.

I use Motoverde Rain-Away on my visor screen and it seems to do the job pretty well. In the inside of my visor I use a Pinlock, nothing beats it, but my glasses still mist over. For them the best anti-fog treatment I've ever used is ProGear Anti Fog Gel. It's expensive for the small amount you get but it really is good stuff and a little goes a long way.

There's also Hawaiian stick but you can't get it any more. I have a stash of them, and I'm guarding them with my life!

Go faster. Seriously, I’ve chosen alternate routes to avoid congestion and increase speed, or filtered more than I would otherwise have done, just to demist and improve vision. I think (but I’m not certain) that a Pinlock helps. An old, scratched and dirty visor will ‘seed’ condensation so avoid that. I’ve used various sprays but can’t tell if they worked. I once explored the snowmobile visors that stinkwheel mentioned, and thought about a custom solution using battery-powered heated wires stuck to an Arai visor (because the snowmobile ones are helmet-specific and probably not suitable for bikes) but it’s such a rare problem even for a speccy like me (particularly now I ride less in Winter) that I got nowhere. Damn, I could have been the next visor entrepreneur like that Adam.
