First: these tubes are from a 2008/09 job, and I am not sure about the shelf life of these tubes. If someone has any information on this, please let me know. If I find out they are "expired" or useless, I will dispose of them (properly!).

Next: I have (21) 28oz gunnable tubes of SIA 478 SIPS Panel Adhesive available to anyone that needs them, for free. They were manufactured by Imperial Adhesives, as subsidiary of Sovereign Specialty Chemicals. These are the "caulk" tubes for joining panels with the lumber.

My location is Elmont NY. If you are interested of know someone who is, let me know and we will see what can be done to get them to you.
