What did they use to seal the metal joints in the trunk compartment in the ‘60’s ?
I’m restoring my ‘65 Rambler Classic and I flicked all the old stuff off. Looks like putty we used when replacing window panes with wood frames.

Thanks

I don't know what they used in 65, but I'd recommend seam sealer now. Great stuff! I'm guessing in 65 it was baby seal juice with lead additive.

I use Eastwood brushable sealer and it looks reasonably close to original.

I don't know what they used in my 66' but it was the most god awful creation I have ever seen. Not only was it all cracked and brittle and really hard to remove but it seems to be porous and act like a giant sponge and all the metal under the sealer was rusted. Some I could simply sand blast other spots like in the cowl area I had to split the seam and weld in new pieces of steel. My 63 chevy had standard black brushable seam sealer that was still holding up reasonably well, the steel underneath it was still in factory primer...

I got as much of that stuff off I could and would never dream of putting the same product back on. It would have been better if they used nothing. I suspect it was an early synthetic product that was just a bit ahead of its time.

PS: After experimenting with the best way to remove it. Heat seems to soften it right up even the hard as rock stuff though it is pretty flammable so be careful.

Ok, what about the drip rail channels? Would Eastwood’s brushable joint sealer work there as well ?

I've used regular 3M seam sealer from our body shop, works well, but at $22 a tube, I've found that PolyseamSeal polyurethane clear or white caulk in tubes works as well or better. And it's $4.97at Menards or Lowes. It's paintable, stays pliable and won't attract moisture like some of the older non-poly based sealers. You can smear it with a finger or a paddle and it looks just like the seams in my 68 AMX. And it sticks like crazy. Another good choice for an adhesive type caulk is GE Lexcel, also in a tube. Will NEVER let go, so make sure you're done with whatever you put it on!

Hi Terry, Can you provide the exact name or part number for the PolyseamSeal polyurethane?
Thanks, Tim
