seam sealers

well, With all this rain in California lately my little leaks have turned into big leaks and I've tried a bunch of different sealers to try and seal up the seams but to no avail. So, does anyone have any suggestions on what to use? or any tips on how to apply it? the area in question is the cowel area i had to replace it when i was restoring the car.

Without tearing it apart to find the spots that are leaking I would suggest these:

A seam sealer is not really going to stop the water but this might;

What do seam sealer do then?

Unfortunately I've tried that stuff too, I wire wheeled the seam then spayed that stuff on thick and it helped a lot. I guess I'm just going to have weld it all the way.

Seam sealer is put on bare metal to seal the seam before it is painted, undercoated or primed. Seam sealer by itself is not water tight.
When you replaced the cowl did you replace it with a new one or just repair the old one? Did you seam seal it then and if so did you check to make sure there were no leaks.
Where exactly is the water coming in, buy the cold air ducts or someplace else. Are you sure it's not coming in through the windshield gasket?

When I replaced the cowel I used patch panels on bot sides... I know o should have just replaced the whole unit. And then a new upper one. And two be honest I'm not sure if its the windsheild gasket. I know the window leaks but have it replaced twice. I guess I never thought that much water would run around the window Ill get the hose out tonight and inspect.
