Query: Horrible Stuff: 1-time use. Impossible cleanup.

One-time use only. Impossible to clean. Ruined more things than 'fixed'.After first use, the straw and nozzle clog with hardened "stuff" and they are impossible to clean with any household solvent.I've never used this product and NOT gotten it on my hands and/or the surroundings. the delivery mechanism and the material itself is impossible to work with. This stuff seems to explode and drip everywhere. Once it's on your hand (and heaven forbid your carpet, wall, clothes), say goodbye. This stuff cures with water and nothing seems to dissolve it (I've tried paint thinner, acetone, goof-off, oils and lotions).Just threw away my 4th can after trying to use it a second time. Never will I consider a Dow product like this again.
