Just as a note to those who attempt the heat gun method, it works wonderful on the RCA tubes which the cataracts, or any tube that has the really severe looking cataracts (the "moldy" looking white perimeter). The "green halo" common to most zenith and sylvania tubes, I DO NOT recommend the heat gun method. You will not get air pockets to form. The pva expands and cracks the bonded lens. Your best bet with the cataract repair on green halo, is to use a hot wire, like 18 gauge wire connected across a car battery. It acts as a "hot knife" and slides right between the crt and lens, this also works well on rcas cataracts problem. The heat gun method is great, but has its limitations.
