He did reply in a very straight-forward and no nonsense way (which I like). In short informing me that the UV filters and blockers aren't really all they are cracked up to be. That 303 and other products protectiong, including Valugards, only offer some resistance to UV damage which is due to the way in which they deflect the UV rays. He really is pretty smart not to mention honest. I was expecting a sales pitch for his product, but received a simple and unbiased answer.
