I've had a sets of grey and yellow silicone, and both on black rubber MPs for abt 4 years, and no issues, but I have wondered about it... Good question. Also have a set of the newer yellow EPDM on an original MP which seems to be OK so far. I remember once somebody mentioning that certain types of those plastic storage containers off-gas and screw up rubber, and I always wanted to know more about that. "Archival" storage of vintage gear, particularly rubber, would be an excellent topic for the basic info section of the site. Not long ago, I was going through boxes in the garage and found some rubber fishing lures that had been tossed on top of some other plastic/rubber somethingoranother, and had basically eaten their way straight down through the pile of it.... not unlike what alien blood will do when you blast one in your spaceship.... Strange how that happens, but I suppose not to a chemist... We got any here?
