    How To Make Your Own Sugru Substitute

    I can see that might be the case. One would then expect that the suguru stuff doesn't use a similar method to catalyze. There probably isn't much moisture in the cornstarch until it is opened. After that, all bets are off.

    How To Make Your Own Sugru Substitute

    Walmart still sells the right stuff. You don't have to smell it to ensure it's the correct product. Look on the label and you'll see it has a "warning" that says acetic acid is released during cure. Acetic acid is vinegar. The wrong silicone has a similar warning, but the release chemical has a longer name I've forgotten.

    Once the caulk-type tubes of silicone are opened, they will cure internally and become useless in a short time. If you have a food-saver type vacuum sealer, the tube can be sealed inside and will last much much longer. Even the low priced hand pump version will increase the shelf life of the unused silicone. The gallon size bags are difficult to find locally, but I checked Amazon and they are available there.It's also possible (but not tested) that any unused oogoo left over could be saved in a vacuum bag.If you use the hand pump vacuum bags, add a piece of adhesive tape on the vacuum flap of the bag to ensure it doesn't accidentally release and let air inside.
