I was pricing out 8115. That takes a special applicator and comes in 200ml tubes. Just how much material did you use? So any suggestions other than the 8115? I am sure you have the tools there in your shop class.
Here is a link to 8115
3M 8116 Panel Bonding Adhesive w 8571 Applicator | eBay
I found this to be slightly cheaper:
3M 38315 Panel Bonding Adhesive w 8190 Applicator | eBay
Maybe JB weld in 5 oz tubes (instead of 2 oz tubes)
J B Weld 8280 Epoxy Adhesive 2 5 oz Tubes 3960 PSI Gray 1 2 HR Work | eBay
I am hesitant on the JB weld as the working time is not as long as the 8115.
Does anybody else have any suggestions?
