So I thought that I had an issue and I noticed a little rust on a few places behind the engine on the fire wall. However, with all the runaway clouds from the tropical storms and hurricanes on the east coast I also have wet floor boards. I don't plan on using seam sealer because I want it to last for as long as possible. Instead I'm going to use windshield sealant after I finish cleaning it all out. The good news is that I have cleaned out half the sealer and the cowl is rust free and the floors just a slight bit of surface rust. Good thing I found this before I replaced the interior. any hints on patching a few places on the fire wall minus bondo and chicken wire are welcome.

Yep go to a junk yard and see if you can cut out the places of the fire wall you need or Like I am using just for now. Fiber glass...
-
Didn't think about that. it would definitely save me some time forming metal but I'm guessing it will be hard to find one good enough to spend the time cutting out....
-
I'm fiberglassing the 1/4" and less spots under the dash and engine bay on mine. Then refilling the getter channel with a layer of fiberglass then cover that with new seam sealer. I have a couple of larger spots above and below the blower box that will need new metal. I also have to replace the floor plan on both sides. My truck sat for 6 years with leaves and funk in the drain channel so it rusted through and let water in the cab. Good luck. I wish someone would make a "seam filler" seal that could be glued in place with urethane for the cowl.

looks like I caught mine just in time. So far I have only one cancer hole that's almost 2" wide and 1/2" tall. Man I wish I had a welder...!!
-
So I made a little progress on removing the old seam sealer and exploring how big the rust hole is
-
After removing the rust that I could actually get to I used Triump to stop the rest of the rust and I plan to use quick steel to temporarly seal the hole since it will be a few years most likely, before I pull the engine and do a modern swap.
-
Oh and some gasket maker to seal it all up. once I'm done permanently fixing the hole I will use window sealant to permanently fix the issue.
-
I would suggest making sure there is not a spot that the water can pool up and stay, especially where you just cut out the rust.

Great minds think alike. I haven't cut the rust out yet though. The hole that you see is what has been eaten away. Good thing is that it is a high spot and I made it a little higher and then sealed it all up tonight. my methods are temporary but how long temporary last depends on if I make rank anytime son.

So, I got the cowl finished and thought I was done...but I found both floor boards soaked after 3-4 days of rain. First though was GREAT, Windshield leaking! Well, I took the seat, carpet and jute out to find rust and a few small holes in drivers floor board and the passenger was perfect but wet...so I tasted it..antifreeze, can't miss that taste! I just replaces my heater core less than a year ago so I wans't happy about that at all.

So I found the leak in the top right driverside corner of the windshield and sealed it ith some GOOP. Got the new heater core today and this time I pressure tested it by hooking it up in the engine bay and ran the temp up to about 220* with a 16lb cap. No leaky, leaky!! sprayed the floorboards tranny tunnel and passenger side firewall wit Duplicolor rubberized undercoat about 4-5 coats. Got the air handler back in just got to bolt everything back together. What funn. Replacement parts now adays stink!!

Glad you found the leak. Sometimes locating it is the hardest part. I still haven't finished glassing in my cowl yet, just had too many other projects to finish. Keep up the good work!
-
I hear ya I'm still working on putting the air handler back inside the cab because I keep seeing little things that I can do while I'm in there. But at least now the outside should be completely sealed and inside as well. I have no Idea how I did histhe first time wit out taking out the passenger fender well...but I did, never again!! Thanks or the encouragement. I plan on keeping this one driving around on mars when ever we ae predicted to be there. Then again the jetsons' thing never happened so who knows
