For UK members, I bought some of this stuff the other day http://www.visorvision.co.uk/shop/index.php?cPath=25 I can vouch that the stuff does work very well indeed on my glasses. I've not had them fogging over once, in the last 3 days, where before if I stopped at lights or for any reason, if I didn't crack open the visor my glasses would fog over.
For US members I think this stuff originates from there, so you should be able to source it easily enough.

You can just slice a raw potato and rub that on your inside visor too

Tomorrow is Thanksgiving here in the US. I'm sure there will be plenty mashed potatoes left over after all the feasting. Could you use those instead?Taz wrote:You can just slice a raw potato and rub that on your inside visor too
