Have the familiar problem with old tail light lenses ......... the "crazing" (crack marks) in the plastic lens, usually visible as those white lines You can't feel any crack on the outside nor the inside.The crazing seems to be inside the plastic. Searching finds multiple ways to correct faded lenses, but none address any procedures regarding the crazing issue.Has anyone ever come up with a way to remove, or hide, these white cracks? The lenses are in good shape, just cosmetically nasty looking. There is a web site touting a successful 'fix' for crazing, but the email or phone contact don't work. Tossing this out to the been there - done that forum members.
