thanks - that's just what I'm looking for. The drop cloths are a good idea too, but I wanted something adhesive for easier installation. Even a small roll is likely to last me for as long as I care to pursue this hobby.

This 3M stuff probably won't have too much tack for easy removal later, plus if I remember correctly, the texture is on the outside of the lens, so this will adhere less, but do a good job of keeping the lens clean from dust, etc.

Appreciate all responses.

Regards
