I need to glue the HVAC box in my car back together (I replaced the AC system, and the only way into it was to split it apart where Ford sealed it). The Goop adhesive I used didn't hold up. Fortunatley, I didn't have the car all back together with the heater core and AC system charged. Does anyone have any recommendation for stupid-Strong adhesive that'll hold up to the heat from the heater core?

3M makes a Plastic adhesive that is some really good stuff. Any auto body paint store should have it in stock. Or you can mix up some 5min epoxy.

gm sealant tht holds basicly every part on our trucks together would work well. high temp chemical resistant and flexible and super strong . 5 min epoxy or most epoxys for tht matter will be to brittle and crack over time.

Happen to have a P/N, or do you think the local parts dept would know what I was talking about?
