I am currently doing some testing for the Fog Tech wipes. I took the Pinlock out of my X-11 helmet, that works fairly well. The Fog Tech wipes does work on the visor and the sunglasses, but not the prescription lenses. I was informed that that was due to a coating on the prescription lenses. It depends a lot the conditions that you ride in, how often you reapply treatment.... I have noticed that the pinlock really only last about a year, before you need to replace the shield and the pinlock (due to scratches and the pinlock no longer being firm). I have one more week of testing with the Fog Tech wipes, it seems to be the most cost efficient way to go....
Sign me up for a test too! I have a Shuberth and it fogs. I have tried the diving lens stuff but it doesn't last long. My pullout visor feature helps when the temp is right. What works best for me is my silk balaclava pulled over my mouth=I also have worn my bike helmet on a snowmobile with the same thing to good effect. Good for helmethead too.
