That's what I was hoping to achieve, but didn't work out for me that way (and with water still leaking into my interior I couldn't see anything cause the defrost didn't work and the windows stayed fogged up all the time. Jeff, I too used silicone on my cowl strip and the guy who replaced the windshild (some *******, me, forgot to latch the hood) said he sees jeeps all the time that leak through the cowl and windshield, but told me not to use regular silicone because it would eat the paint/ rust the steel. Oops, I pulled it back a little and sure enough, there was rust all the way across where I had the silicone. You can get weather stripping glue/ sealant at the hardware store that won't do the rust thing. Just check it out (read the directions/ specs) before you buy (and maybe ask the counter guy). OH, and I also (when the jeep still leaked) took a piece of hard plastic and cut it to fit the countour of the vent duct (where I thought the water was coming in) where it looked like a little Dam in there, and there was no way water could get in. It is siliconced around the sides and bottom, and is about 2" tall, so fresh air can still get over it, but the water would have to be 2" deep in the vent to go over it. Might try that before you seal it off too.
