68 4-door "Sleeper"

What did you use to make the insert for the vent it is a really great idea?

"The other thing that I have been working on is the driver's side vent. I showed before, the rust damage. (Picture below).


Instead of trying to create a new sheet metal vent and trying to make it look perfect, my goal is to make it last until I am dead. So, I fabricated a new vent, and then, I put a bunch of epoxy on the "lip" to seal it in there. It can't be seen and I will be dead before it rusts through. So, I am OK with my "fix".
