Letting water in!

Hi,
I'm sure this has been covered on here before but I could not find an answer. I was getting water on the passenger side floor and looked all over the dash and couldn't find a leak. After taking the carpet out and drying things out it appears that somehow the water is coming up through where the roll bar meets the floor board. I tried putting a sealent around the seal (though it was a really cheap sealent). The water continued coming from under the new sealent. Any ideas on fixing this problem. I live in Seattle so keeping it out of the rain is not really an option.

Also I was contemplating taking out all the carpet and maybe putting a spray on truck bed liner down. Anyone do this with good results?

Thanks, Josh

I have a jk and have not had any water issues. (idaho). last summer I took out the carpet and bought a few cans of the herculiner. Its a ton cheaper to buy at walmart than anywhere else. I like it now, but hated it then. I suggest to do it when you can leave the top off for a week or two. You"ll be getting high off the fumes. I put on 4 thick coats and it looks great. All the kids crumbs and juice can be rinsed out with a hose. the JK's have drain plugs all over in the cab.

Sounds like it was worth doing. I'm hoping to do it this summer on one of our few sunny days. The only thing im worried about is if water continues to get in at the roll bar seam would it sneak it's way all over under that liner? So many dumb questions. Oh well. Thanks for your response I can't wait to get that started!

The liner is basically paint. Once it's dry and as long as it's properly applied water won't get under it. Are you completely certain that water is getting in UNDER that? Seems pretty unlikely to me. I also live in the greater Seattle area - and have never seen that sort of problem on my 97.

Well I have taken it through an automated carwash and it doesn't seem to be leaking from anywhere else. I first thought it might be coming from between the hard top and the body at the first bolt area but couldnt find any leaks there. That's when i saw water slowly coming out of the welded seam around the roll bar. It is not a bad leak what so ever. The only thing i could think of is maybe there is a crack in the welding on the back side of the rollbar. Maybe I should just be thankful that this is the only leak I have. :)
Thnaks for the info about the liner!

Your best bet to stop a leak like that is to fix it from the outside rather than the inside. Water can push sealant out of the way and get in if you try sealing the inside only. Also, to find the source of the leak, have someone outside with a hose, starting underneath, down low, and gradually work upwards until the leak shows up.

Also, there is a TSB out on the drain for the air conditioning unit that extends the drain spout under the hood. I had to do that on my '02 TJ as my floorboard on the passenger side was soaked most days...

Although, I am sure you are not running the AC right now!!

I wonder if I can just roll some coats of that Herculiner on the outside where the roll bar bolts on. If i can get to it from underneath. As far as the drain spout for the AC when I first noticed the leak I put a hose on the spout just in case that was the cause. (It wasn't) but it can't possibly hurt having that done for any future problems.
