how do you keep them on without the lids? and what is in the canisters that would rot the screens? i've never heard of that.
I use my smal dpa screens and gently push them into the cans....very tight fit....when I pull the mics out the scren usually stays put and when it is pulled out, the screen has the shape of the cans...kind of funny till it bounces back.
Not sure why the "rot"...the screens started to get gummy...and the white cans I used turned yellow.....I was talking to another and they mentioned screen rot too.....later on this board someone mentinted that they had to be washed out due to the chemicals of the film.
so now I only use the cans in transit and not storage.
oh and how do they stay on....very welll ;-)
peace
