Morning Fellas I have a can of Unibond 800 that I bought about 2 years ago for some thing that I dont rember what for but it never got opened & used it has benn stored in side room Temp. I have read that it can go bad with time turning clay like, has any body used it after setting ?

Best way to tell is mix up a small batch and glue 2 pieces together

If it is still liquid use it, when it goes bad it sets up like concrete.

Here is the best place to buy unibond800. Awesome price..
