Carbon Fiber Helmet Strip

Now that the 'Carbon Fiber Helmet Strip' tested in Indy car this weekend proved its value to Martin Plowman and James Hinchcliffe, what exactly is it? Yea, I know it is a piece of carbon fiber attached to the visor.



Is it available? Can I purchase it? Can I make one to fit my HJC? If so, how many layers in what orientation and how to attach it to the visor?
