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.
just wondering if there's a handy convenient way of preventing the caulk
from hardening in the nozzle.

b.w.
