69 battery door compartment seal...glued?

[Gary H.]

Is the rear compartment seal on the battery door supposed to be glued in or loose?

If glue...I assume clear silicone?

Yes, it is glued, it is not as visible as what is on the doors and hood weatherstrip. Clear silicone should work fine.

It was originally glued in place with a neoprene solvent cement (i.e. similar to what we know today as 3M Super Weatherstrip Cement).

Is that yellow or clear?

The piece of my battery compartment sealing foam that came loose on my 1970 had an adhesive material that was sticky. The kind of thing one would peel a waxed protestant paper off of before pressing the material in place. It was definitely NOT anything like weather strip cement. The foam on the top of the radiator core support has the same adhesive on it.

That surprises me. First of all, GM says that neoprene solvent cement was used for the battery box seal. Second, I have an NOS GM #3918669 seal (photo attached). It has no evidence of any PSA (pressure sensitive adhesive) provisions.

Also, my 1969 radiator support air dam ( 3 piece style) was attached with neoprene solvent cement. The "squeeze-out" was obvious.

I can only guess that the method of attachment of these items changed between your car and mine -- 3 or 4 months. I don't have my 1970 AIM in the house, and I doubt I will have the opportunity to get to it before leaving for the winter regional. At the moment the garage is so secure even I can't get in.

Thanks for remembering the name of that glue. I just couldn't think of it as I was responding.

I have a service replacement like the one Terry describes. The outside of the package says, "Sold to DW 6-4-81." I think it was in a box of stuff we bought from an individual when Dick was restoring the L88.

Is it an "un-jointed" type of piece (i.e. die cut from foam rubber stock so that there is no joint where the ends of a strip come together) or a continuous strip which requires a "joint" where the ends come together? Also, does it have pressure sensitive adhesive with the necessary paper protective strip?

Hi all,
my July '69 has PSA and has a join.

My 68 definitely used some type of factory applied glue and not PSA for the battery compartment seal. The squeeze out is visible in the attached picture. I don't know the original color of the glue but you can see it has yellowed over the years.

The "dark yellow" color seen in your photo is very typical of aged neoprene solvent cement. When new it would have appeared virtually identical with the color of 3M Super Weatherstrip Cement.

According to GM, neoprene solvent cement was used to affix the seal from 1968 through at least 1976. However, it appears from the reports of others that a PSA type seal may have been used at some point.

I replaced the seal on my 1969 many years ago and I just don't recall how the original was affixed.

I suppose GM may have tried PSA type seals for a short time to see if it would shorten the assembly time and then went back to the original way....

Greg -

Couldn't resist addressing this - having spent a good hunk of the early part of my GM career trying to cost-justify initial product designs and product changes that would simplify assembly and reduce assembly tooling cost and direct labor, I can guarantee that Chevrolet paid virtually zero attention to assembly cost savings; the bean-counters considered GM assembly labor as a fixed cost. All that really mattered was the piece cost of parts from suppliers. If a supplier suggested a change that would actually reduce the piece cost of a part, Purchasing and Engineering would jump on it, and the contract would be renegotiated at the reduced price if the change was implemented.

Chevrolet Manufacturing was like Rodney Dangerfield - "we just didn't get no respect".
