B&L do a coating called rainguard on their scopes.
is this coating available as an after market product?
There is a product on the market which is designed for windows,which is similar.

E-mail B&L about retro-treating a scope.

The product to which you are referring might be what is called Rain-X here in the states.

I think adding rain-x or most similiar after market products, would put the multi-coat optics treatments from the scope maker at risk. Many glass cleaners even can harm the coatings from what I understand.
