RadTech (http://www.radtech.com) has announced the ClearCal
Anti-Glare Film for glossy displays. It purportedly improves the
viewability of glossy glass displays when used in brightly lit or
outdoor environments.

ClearCal films combine a tempered two-mil matte finished,
anti-reflection layer, permanently laminated to a three-mil flexible
transparent base. A blemish-healing siliconized adhesive provides an
optically-correct, yet removable bond that conceals existing surface
defects like abrasions and scratches.

The siliconized adhesive is permanently bonded to the base layer and
will never leave any residue behind if later removed, according to
the folks at RadTech. It’s available in sizes for the 13-inch
MacBook/MacBook Pro, 15-inch MacBook Pro, 24-inch iMac and 24-inch
Apple Cinema Display. Unfortunately, there’s no pricing info on the
RadTech web site.
