    Hello Buick fans what’s the black sealant used for the fire wall and A/c called?

    Use 3M Strip Calk - #08578 (black). Used to seal the AC Evaporator box halves and also where it contacts the firewall.

    DO NOT use windshield butyl roll material.

    X2 on the 3m strip calk. Why not use the windshield stuff? Seems like the same stuff to me. Just curious why you say that.

    You'll never get it apart without breaking/destroying something.

    I used it and plan to never take that apart again.
