Expensive Chapstick?  Overpriced
I used this on my Oakley Gascan sunglasses and all I could think was "why is this so expensive?".  I think they could knock off about $5 from the price.  This is white so it's visible on black sunglasses like my Oakley sunglasses; so limit to the inner part if you don't want it to show.  It seems to work ok but I didn't notice too much of a difference and it does wear off after a few hours in the sun.  If you're having major issues then I can see how this might help keep them up but it should not be this expensive.  It also warns on the package of possible skin irritation which I've seen from the reviews that some people have been affected.
