1957 firewall gromet sealer compound

[Dan P.]

The AM calls for part number 3686628 which is the gray body caulking .The fire wall grommets on the car when I took it apart appeasers to have a black sealant on them ??. Like black roofing tar. Which is correct.

Re: 1957 firewall gromet sealer compound

my grommets off our three 57's , as well as the 55, 56, 61,61 and 62 vets, were sealed with a black caulk. you would think that if they were originally gray, there would be evidence of grey color buried within a cross-section of the caulk. I've used 3-M strip caulk during the above restorations. mike

Dan,
There is a good article in an old Restorer magazine with regards to this. I will send a copy to you.

Finally got around to pulling some of my original caulk apart on mid Dec '56 assembly and it is black throughout.

Dan,
The article in the Restorer Magazine with regards to the grommet sealing is in Volume 37, Number 4 Spring 2011.

In case you don't have that Volume I've scanned it and will send to you on a PM.
