We go through a lot of stickfast.. I use the two ounce bottles, but also sell the one ounce bottles.
Mostly, if you "burp" the bottle and then wipe off the tip, you should be good for the cap. Once the cap starts getting stuck, i just throw the cap away. The glue will be fine with the cap off for weeks if not months. Never had a bottle last more than a couple of months I would guess.
During show season, i don't get as many bows built so the bottles sit a lot. Never had an issue.
