I am replacing the rad core and both gaskets on my 1938 F-20. Got the old one off, and it appears that the old cork gaskets got a coat of permatex gasket adhesive/sealer on them....I believe it was called aviation gasket cement. You remember the kind, brown, thick, goey, and had a very particular odor to it. Used to come in a small can and the screw on lid had a brush on it. you would "paint" a thin coating on the metal gasket surfaces, and place the gasket on one surface, and it would stay in place until you put the other piece on, and got the bolts/nuts started. My job as a kid, was the "painter"......dad would do all the gasket placements. last comment, the gasket was not leaking, the core was. Core was pretty rotted at the back bottom.
I can certainly use the same stuff again, but wanted to check in here to see if anyone had any pet process. I am not a huge fan of silicone, but will listen to what people have to say before I start.
Any thoughts are welcome, as I have a full day of cleaning and painting the cast parts. I also have a couple of twisted off bolts that I need to remove which will make the process a bit longer. might flow over into a 2 day project.
