just wondering, is there a good technique out there for capping a open tube
of silicone caulk? i usually put on a couple layers of duct (or some other
plastic) tape. the caps that come with the tubes don't prevent the caulk
from hardening in the nozzle. a while ago i saw a thing in a handyman's
magazine, the guy would cut a hole big enough to insert the nozzle in a
used
35mm film canister and fill the canister w/ grease and put it on the
nozzle.
i tried this a couple times and it was a huge mess and it didn't even work.

Heavy aluminum foil isn't too bad. Whatever it is, it must be
impervious to moisture and CO2.

We just put a two-and-a-half inch deck screw in there, and let it
harden. Next time, grab the head with your vise grips and pull it like
a wine cork. Of course, we do Stainless commercial kitchen welding and
repair and may use more Aluminum caulk than a private user. Maybe this
technique is bad for long-term storage... YMMV.
