I have been using http://www.prosoftbaitglue.com/index.html

But the bottled gelled up on me even though I was very careful in not
contaminating the glue with water, etc.. Three spouts hardened up on me
even though I rigged a pin plug for them. This stuff is expensive.

Is there a more manageable glue for holding and repairing Yamamoto type
and other soft plastics?
