DSE Firewall Plate Installation

Option 2 worked for me. I used a two part seam sealer.

Seal it, less distortion to deal with. I did not use seam sealer, I stepped up and used panel adhesive. You will tear the sheetmetal before the adhesive lets go

So, Mike, you must have ground the lip pretty much flat so that the plate fit flush with the firewall in order to use panel adhesive, right? That's my dilemma right now. The plate fits great, but there's about a 1/8" - 3/16" gap between the firewall and the inside of the DSE plate when looking from the heater box opening inside the car.

What kind of sealer is best to use in this area? I'm using a 3M urethane sealer everywhere else. The kind in the black sausage tube.

Correct. I ground the lip until it fit tight. The panel adhesive I used is in the automix tubes and is 2 part requiring a special gun to apply.

The part # and name is 08115 Panel Bond and yes the metal will fail before the glue. This stuff is so strong GM and Chry made 3M make 08116 that is not as strong so the glue fails before the metal.

Got-R-Dun! I stich welded it about 20-25 times around the perimeter and then seam sealed it. It came out really nice. Really cleans up the firewall for sure.
