How did you reseal the firewall after replacing AC lines on a fsj wagoneer?

Built my own AC lines, but had to cut the firewall grommet apart to get the originals out. What are you guys using to seal the old oval hole around the new lines ?


Heres the rig in question

Hi, I'm getting back on Naxja after a several year hiatus. Im not just into the XJs, but also the SJs.
So to fill that hole, which ive never had to do yet because my a/c is still ok, but could you use the light duty expandable foam? Just throwing that out there. I know the heavy duty stud can be pretty aggressive/ solid.

Heavy duty stuff, that is. It expands way too much and tends to crush things.

And keep in mind, it can be trimmed with a razor to whatever shape you want after it cures. That's the nice thing. It also takes paint as well!
