Fedup with sealer congealing around the top of the can? Most of us decant it into a bottle, I put mine into a small airtighht container, a food container from the £1 shop will do, although mine says Playdoh on the top as we have just sorted my Grandsons toys out and it was headed for the bin.
For the really small amounts of glue use the top from a milk container and apply it with a cocktail stick.
