Cowl repair

Thanks for the info. I thought My 65 barracuda was the only one with that problem. Glad to find I'm not.
I can't believe the areas where rust apears on a solid looking car. I pulled the 3 piece trim behind the rear window to prepair to paint and found a 2 in. rust through that I also have to repair.
A older gentlemen I met had told me to use the roofers asphalt and gutter material or alluminum to patch a small area in the floor. I have totally stripped the interior to look for any other areas that need help.
thanks again
