I don't think your URAC was too old but I do think you used the wrong thing to degrease with and suspect this caused your failure.
Eric - This is what I thought originally, but the second glue up from the same can of URAC did not take either - and this time there was no de-greasing.
I am going to try to get some DAP. If I cant find it locally, I will use the TBIII as you guys have suggested. I will let you know how it goes.
