Not with SMC, that you can famously stub cigarettes out on. Assuming you actually mean silicone products. Silicon/silica products would undoubtedly wipe out the glass, never mind the coating. I was listening to a radio programme yesterday where a gent was expounding the virtues of his selfcleaning and water dispersing glsss. I was driving so not paying complete attention but I did (after checking the date) note that he thought the price increase of 15% was too much. Maybe for industrial use but I would pay that for household glass. Something like that would be good for waterproof cameras. It stopped water beading by some combination of physics, chemistry and satanism. I always carry a Pentax cloth with me for wiping the zoom90wr lens cover when I'm using it. Not perfect but it works for me. Any detergent would help the process if applied in small amounts. mike > > Frits Wüthrich wrote: > > >A friend of my in the UK asked me this question: > > > >"Was wondering if you could help me.
