Its a carpet cleaner ..really.. Well heres a prob. Im gonna tell you all about and it sucks to.
I have a water leak you know and its stopping me from putting in seats and carpet, ( I dont think im using carpet maybe just a piece over the drive shaft hump with a border sewn around the edge then screwed down with self tapping drywall metal framiong screws) ..Sealed the bettery tray last summer thought that was all the problem there was,
took a vacation after thanksgiving came back after x-mas and it was wet,Im reachin up there and when were driven theres air coming in from somewhere ..think thats where the water is comong from cause the insulations wet up there..

if you knew where the hole's were you could use expanding caulking foam,comes in aerisol cans ,is used for caulking around showers and tubs

I've seen patches fail... even if you use fiberglass, water just seeps around the edges and rusts underneath. Only permanent solution is new metal welded in.

I have this problem on my 931, it's got massive corrosion, needs structural repair. That and the lack of a proper full interior are its only real problems...

caulking will minimize the flow until a better repair can be made

I too had a wonderfull leak from the battery box. First I removed all the paint with an electric wire brush, then neutralized the rust with "ospho". I then layed down several layers of fiberglass and resin trying to keep edges up high where water will not easily reach. Finally, and most important, several layers of an elastometric paint, such as used on decks or roofs. It must remain flexable when dry. I found some in red and it blends nicely with the car color. I don't see why this shouldn't last forever. It is critical to keep moisture out from between the fiberglass and the metal because this is what delaminates the fiberglass. I plan on touching up the elastic paint once a year. Also don't use so much resin as this will lead to cracking. Just enough so the fiberglass can flex a little and handle some vibration. I hope this helps.

fiberglass is NOT water proof,on boats a gel coat is what makes them water proof.you need to add a water proof sealer over top of your fiberglass patch,preferably silicone or epoxy.

On my first 924 I just used tin, rivets, and GOOP. Try finding 'GOOP' in your local car store. It fixes everything.

GOOP!

No shit.

Well before i fixed the battery tray ( its not leaken there I fixed it good with a wire wheel on a drill and snips then reall glassed good with cloth and resin then paint) I took out the heat exchanger and I was in a hurry anf one of the rubber grommets failed on me that keeps a air tight seal around 1 of the heat exchanger tubes(through the firewall)
that might be it...

Evidently, one of the PO of my '81 did a patch with sheet metal over the holes and some kind of rubbery asphalt type sealer. Didn't work. Looked okay, but let lots of water through. Yeah, like someone else said too. All this type of repair does is allow water to get in and hangout nice and long, thereby rotting the metal even more.

Mine was a mess. Getting that asphalt stuff off was a major pain. Had huge holes large enough to stick multiple fingers through. Didn't think it would be structurally sound enough to support a battery. Used the POR stuff though and it seems to be working.

I won't go into detail how it works. Just go to the site. I just coated everything a couple of times to protect the metal/rust, then started building up lots of layers using fiberglass matting to help. Good luck.

I had a leak on the drivers side I couldn't find utill I pulled the dash and pointed a hose at the drain tray. Once you find the leak try Marinetex you can only find it at boat stores. Boaters use it to repair cracked engine blocks the stuff is amazing.
