Heat from door hinge
Once the 65 327-300 air roadster is warmed up and I am driving at speed I get a tremendous amount of heat coming in between the front of the door and the dashboard on the drivers side. I got under the car today and removed the small splash guard and saw that there is a large (1/2-3/4") gap between the fender and firewall. For the fun of it I got my air hose and blew air into the gap, my wife got blasted on the door hinge side.
question:
How do I fill this gap? The air temp is big, it's engine and exhaust heat. (Actually I was thinking about Great Stuff and see it's only rated at 240F)
I look forward to your responses.

The front end has most likely been replaced and the bonding from fender to firewall was not used. Seal it with something that stays kind of flexible, the heat will never be all that great there. One of my previous cars had the same issue and I never did try to fix it. It does heat up the interior very quickly, particularly the driver's leg. It was an a/c car also and the a/c couldn't keep up with the heat coming in. Whatever it takes, you need to seal that gap right where the firewall meets the fender, probably on both sides.

Has anyone used great stuff in this situation? Would you recommend it? Anything other solutions? what was your experience?
Dumb question:
Is it possible to get a bonding strip in there?

There was another thread on this a few months ago. Very common on cars with front end replaced. It should be filled with bonding adhesive but that is kind of tough to do with the body on the frame and the engine in. You could get some Eklers bonding agent (only because it is thick bodied) and some fillable caulking tubes from West Marine supplies and fill it with bonding agent after cleaning the surfaces. I would tape the backside as sort of a form. But, I'm just not sure how well you can get access to work a caulking gun in there with an assembled car. From below would probably give the best access.If you want a more temporary fix get a strip of foam weatherstriping sufficiently thick to compress and stay in the gap and push it in to fill the gap.
