More on my Qwest anti-fog quest…
I read a lot of good things about Salclear - created and used in the Isle of Mann. I ordered some TT anti-fog from them, but it simply wouldn't work - it dried into a haze I couldn't see through. Dave Salter, the guy in charge, really tried to help me with the problem, but in the end we couldn't get it to work on my visor. He sent me, free of charge, a couple bottles of his "better" formula, Vision+.
Initially, it worked very well, but a year later, the liquid seems to have lost its potency, and the other day in a cool rain, it really didn't work at all, just a few minutes after applying.Some local old-timers who have raced forever swear by the "Foggy" breath guard by Respro - it's a mask that blocks your breath from reaching the visor. I bought one of them, too, but I have never gotten it to fit my helmet and my face well enough to make a good seal. It attaches with velcro to the soft helmet lining, and every time I tried to remove and reposition the mask, the mask's velcro loops shredded the liner more and more. And, if you get an itch on your nose, you're screwed! I finally gave up on it. So, after a year of riding, I still don't have a satisfactory anti-fog solution.
I
love the comfort of my helmet, especially after trying on some other brands and styles, but between the quick-fog visor and the ungodly wind noise when my windscreen is mounted, it's a tradeoff. Pinlock visors are available for it, but between the visor and the shield, it's very expensive! Always looking for the cheap alternative, I guess...
*Edit - in fairness, I applied the Vision+ this morning to ride in 39 degrees F - it worked just fine. I don't know what happened on the rainy day, but I couldn't even see safely. Today was fine. I guess it has to be applied regularly - like every day?
