Ralph,

Another option I have tried is the black neoprene stuff they sell in diver 
shops, which they use to repair diver/wet-suits. I had limited succes with that 
though..I am realy surprised about your observation that these pinholes did not 
interfere with the actual exposure! Maybe I have been to hasty with replacing 
my Toyo Field 810M which was realy puuctered with a lot of pinholes..;-)..

Best,

Cor
