    Noticed my carpet getting wet lately...pulled it out today and I'm getting water in where the fender wells and the floor pan meet. What's a good sealant to use on this? I am thinking about Herculining it afterwards, but want to get it to stop leaking first

    Permatex makes a really cool product called "Flowable Silicone". It's designed for windshields, but I think it might work for your application because it is fluid enough that it will seep into voids before it starts to cure.

    It might be worth looking into, brother......

    do you think it would be better to try and get the old stuff off if possible? Looks like that would be a pain, but I'd hate to not take it off and have to redo it later on /forums/images/graemlins/confused.gif

    I've used the stuff on the windshield of an old Ford I used to own. I tried to silicone the sucker a couple of times and finally got good results with the flowable stuff. I never bothered removing the old silicone before I applied the flowable, and it worked fine.

    Like I said before, this stuff settles into low spots and voids so if there's a leak it'll find it whether there's old silicone present or not. I personally wouldn't bother stripping the old silicone out........

    Depends on how big the area you need to patch up is, but some JB weld would be perfect. It dies super hard and is very bondable to pretty much any clean surface. I think you can pick up a package of "JB Quik" at any parts store for around 5 bucks.

    3M's # 5200 is used for underwater marine applications and will seal anything!!
