My rusty cowl repair so far...
I realize it isn't the way the professionals would do it. My goal is to at least stop things from getting worse. It is already a problem the floor pans are gone because of it. I would like to get the car back on tje road sometime soon. I've barely been able to drive it for the past year. Luckily the bottom pan is solid. I'll probably go with fiberglass instead of coffee cans. Then waterproof with rubber seal. I've got roof tar too. The key is to keep the water flowing out the drain holes. I will be replacing the windsheild eventually. I may do it the right way then depending on how it holds up. I'll keep updating my progress.
