Sealing a gap

[hopsBB]

I was going to take of my rusted up muffler and I noticed some metal hanging from the po's fix.Its right where the floor board bends up into the firewall and it a hard area to get clamped down good and try to weld.I was thinking about trying to put some kind of sealer on it but I'm not real sure if its to big of a gap.

There is another spot on the drivers side right at the tranmission hump and the firewall and its even bigger than this one.I don't have a lift so I can only set the car up on jack stands to work up under it and welding up underneith it is already a pain.Any ideas?

They had one peices screwed down on top of the one you see in the pic.I yanked that out and I found this piece under it.Its welded on the top side,they just covered over the whole you see with a bigger peice of metal and didn't do anything to the bottom side.Its hard to get up in there,so I guess thats why they just left it alone.Sorry about the pic being kinda fuzzy,I took it in a hurry before it got dark.

Well if it's welded and solid enough to satisfy the (YOU).then maybe go underneath with a punch,"maybe even a chisel" and a hammer.and carefully drive the opening's edges as close to the upper patch as you can,this way you're not trying to seam seal as gig of a gap.hope I'm on track with what you're asking!

I can't tell how big the gap is from the photo. A good 2 part seam sealer can be applied in heavy beads and then smoothed down with a brush. That should seal it up and prevent moisture from getting in there and causing more problems later.

The gap in the pic isn't all that bad but the other one I'm talking about it probly 1/8 or so give or take,but the other one has about 1/2 in of an over hang.So if I beat it closer together then put some sealer on it do you think I'll be good?

[63t-cab]

I would say yes it will be good to go.

I agree, beat them together as close as you can and then seal em up.

Why would something like urethane roof sealant not work on this?I would like to know.I'm not the talking about tar stuff.I've got some gaps and holes I need sealing up to.

This floor has already had the rusted metal cut out and a patch welded in. It just wasn't done very well. The new metal didn't fit tight to the original metal. So now he needs to seal between patch and the original metal. Seam sealer is the right product to do this with.

If you are refering to your floors post, you said that the rusted metal had already been cut out with a grinder and now you needed to patch the hole. If you use the body panel adhesive and fit your metal nice and tight, you won't need seam sealer because the adhesive takes care of that for you.

I'm just curious if it would work in general for something like this.Not just my post.

Don't know if it would or not.I've heard of ppl useing roof tar,but I don't know about the urethane stuff.Kinda makes me wonder myself.

I used a trunk seal product and I think it was made by 3M. It worked great on a gap between the trunk floor and the inner fender well.

I tried the roofing tar on the floors of my mustang when I was in college and didn't have any money. It worked in that it seemed to stop or at least slow down the rust. However, now that I am going back and trying to fix things correctly that stuff is messy to get rid of. I don't know about urethane based stuff, I've never even used it on a roof.
