Gorrilla Glue is different than Gorrilla Super Glue.
Like the trade marked 'Super Glue' products, Gorrilla Super Glue is a cyanoacrylate based glue, while Gorrilla Glue is a polyurethane based glue.
Both are activated by moisture, which we have tons of here in our atmosphere, so it's great for curing, but that also shortens the shelf life and storage life.
Gorrilla Glue is said to have a sealed shelf life of only 6-12 months, and once opened, it all depends on how weel you seal it and the amount of moisture that has enetered the bottle. Can be as long as 3 or 4 months, or can be a s short as 1 month.
I can't find ANY information on how to dissolve polyurethene glues, but as with cyanoacrylate, acetone (aka, nail polish remover) works well.
Gorrila (the polyurethene) is said to give you more working time, whereas most cyanoacrylate are usually fairly short, unless the product has been formulated with other compounds to lengthen the curing and working times.
Note: Most cyanoacrylates dry to a hard, brittle finish and affords little or no tolerance to flexing or impact of any kind, but there are cyanoacrylate formulars tempered with rubber compounds to give a more flexible glue.
Hope this helps some. For exact product specs, please refer to specific manufacturers. I just typed that from the top of my head.
