Topic: 1968 GT 390 (San Jose) Tail Light Lens coating over screws

[bullitt68]

I tried doing a search but was not able to find any reference to Tail Light Lens coating over screws. Is anyone familiar with a process to replicate. I was surprised to find this as I have not seen it before and want to confirm if this was a factory procedure.

Thanks

Interesting. I’ve never seen it before either.  My guess is that it is not factory correct.

I have taken dozens of these apart and have never see that sealant. There is problems with water intrusion around the tail lights I suspect that a PO was trying to seal thing up better.

It is odd as it is not a daub of silicone or sealer. It is very uniform and was really on there. Fairly hard substance and they are the same size and perfectly round. I guess anything is possible, but it looks very factory like to me. I have never seen it before either until now. Another one of the unique mysteries of my car. I can't imagine why a PO would apply it since the car spent its entire life in the dry California dessert.

On a few screws, the tips are dipped in a wax-like substance. It's a possibility. The tail lights were delivered to the plant assembled, so the 68 Electrical Assembly Manual does not show the hardware (AM0023 pg 31). The 75 MPC (ILL Sect 134 pg 15) shows 372856-S (UU-79) screws used to hold the assembly together but that part number does not clearly identify finish or if a sealer was used.

Thanks Jim I am pretty sure that these tail lights have never been apart before as the rubber seal were very hard to remove and all gaskets and screws looked to be untouched in any way previously. all gaskets and seals have part numbers intact
