I have Clarity Dfog, and it sucks. I've tried apply more, applying less, buffing more, buffing less. It just doesn't work.

 

Plain old car wax, works on the bathroom mirrors so I would guess it would work on the shield.

I click up on the Shoei or the vent right under the shield.

 

I just slightly open the shield (one click on my RF-1100) and just like that, there is no more fogging. I don't mind riding like that either. But it would be nice to find a really good and practical fogging solution.

 

+1 just make sure you use it sparingly like the product directions say. This stuff works great and is good for me all the way down to 34 degrees, which is my riding cut-off.

 

You're 4/5th of the way there with an RF-1100 helmet. Once again, Pinlock is the only thing I've found that works all the time, every time without even thinking about it or having to "re-apply" anything.

I have no business interest in Pinlock, just someone who's grateful for having discovered the system. If it's cold or inclement enough to warrant a face shield, then I've already switched from a 3/4 helmet to a Modular (Shoei Multitec) and typically have a Pinlock-equipped faceshield installed: clear faceshield + clear Pinlock insert for the commute, or tinted faceshield + clear Pinlock for daytime-only riding. Also, if you purchase a Pinlock compatible faceshield, you can use it as a template for drilling holes for the Pinlock eccentric pins in other faceshields that you already have. Pinlock inserts typically come with the eccentric pins. It's just a very slick system.

I still have to use anti-fog treatments on my eyeglasses, which can occassionally fog up when it's in the single digits or the humidity is really high + cold.
