Haven't checked in here in a long time. Greetings to all the regulars. I've got a Vivitar cicular polarizer (77 mm) stuck to a Firecrest IRND 18 sunfilter (77 mm). They seem to have become welded together. Any advise on how to get them apart. Tried putting on some heavy duty latex surgical gloves and seeing if that would give me a better grip, but no use. Any suggestions?.
