Goop between body panels

I did a search but couldn't find it. What is the stuff between the body panels and where can I get it?

 

i seem to remember somebody saying it is something like underbody coating. or maybe i am just dreaming that.

 

I think you can get it at NAPA. It's called "seam sealer" or something like that. Also, I have a box of 3M stuff that I bought years ago that's called "Seam Sealing Putty". It's permentally soft and comes on a paper backing about 12" long and 5/16" wide. You peal it off the paper and place it in the joints, or you can "putty knife" it in on an already installed panel seam. I used it on my British sports cars that had no sealer in the bodly joints. Always a point of rust if not taken care of. Oh, it's paintable too. I just pressed it into the joints, smoothed it with my finger dipped in a bit of regular paint thinner, let it dry well, and touched it up with paint with a small brush. When I sold my TR6 after 26 years of ownership, it was still there and good.

 

Thanks!! That's what I need.

 

David-
If you are looking for something a little more controllable, you could use a heavy duty drip check sealer available at any FLAPS that sells auto body supplies. I've used both the seam sealer and drip check sealer. The drip check sealer dries hard, whereas the seam sealer is designed to stay soft, IIRC. Just another option...

 

Dennis: Is that the stuff that they used on the old cars that had drip channels above the side doors? That would work good also.

 

A CJ has the beige putty between the front fenders and body, for example. Not many places to use real seam sealer. Depending on the brand, seam sealer will set up hard or flexible, but I'm pretty sure it'll set up. It's main characteristic for body work is that it's paintable. Seam sealer is used to fill gaps in the body, like along the fender joints on the back panel. Seam sealer will set, unlike putty. I think the stuff you need is called "rope caulk" and is mostly clay and linseed oil.

Eastwood has several types of seam sealer http://www.eastwoodco.com/shopping/...ttribute15=0&attribute16=0&RS=1&keyword=caulk

Rope caulk can be found at the home center; used for sealing windows and doors.

 

Tim: I think that 3M Flexible Strip Caulk is what I have used. It always remains flexible, but is paintable. GM seemed to use it before assembling the body panels. What squezes out you simply wipe off.

 

Mike: Don't think so, but it would work well also. If I remember right, it is used to seal roof seams and such. Kind of "High Tech" for our Jeeps!

 

It sure is. I got turned on to it when I was restoring an old chevy pick-up. Works real good.

 

Dennis: Cool !!! Now I know what to adk for.

Thanks !

 

I have used the seam sealer, it came in a caulking tube and I used my caulking gun. I also have some stuff that is kinda like "fun tack" if you know what that is. This stuff is dark gray sticky putty that stays flexible. I believe it is a plumbing thing, dumdum putty sticks in my mind for some reason. It comes in a plastic wrapper similar to C4 (errrr, or so I hear....)

 

Thanks guys. I'll hit the shop on Monday and see what I can come up with. The stuff on my Jeep is still flexible (after 24 years), so I'd like something about the same.
