After removal and extensive birdcage repair work, I am just about ready to re-attach the nose to my 74 coupe. When removed, the top of the firewall was attched to the cage at the top with 12 pop rivets, and bedded in a pliable black sealant....does anybody know what it was, or have suggestions on what to re-bed this joint in? Thanks for the help.

Re: Firewall To Cage Adhesive
I like "3M Urethane Windshield Adhesive", which is available at any good automotive or body shop jobber, for all birdcage sealing/bonding applications. It comes in a standard caulking gun tube, is black, skins/dries fairly quickly, is very difficult to clean-up, and is expensive at about $18.00/tube.
The stuff is good for life, though.

Re: Firewall To Cage Adhesive
I would agree...this urethane product (051135-08609?) is a good choice IF IT IS PAINTABLE. In this application, whatever sealant you use SHOULD be paintable.
This product can be smoothed by "paddling", dries to a hard surface, but remains flexible and very strong. For installing glass, it requires a primer; in this application, you can probably skip the primer because the adhesion to the materials is a secondary consideration IMO...just clean the mating surfaces well.
You will have a little working time, but this product is pretty fast...better get your firewall in position, and install three or four rivets across the cowl to quickly pull the firewall down into the sealant, then finish the riveting.Comment

Powder Coating...
In your previous thread, I believe you said that the body frame (birdcage) had been powdercoated. If that's the case, you should ream the rivet holes to confirm the pop rivets are going to fit before you squeeze the sealant. Powder coating will reduce the rivet holes to less than the diameter of the rivets, and you won't have time to mess with that once the sealant is applied.Comment
