Windshield pillar post bottom sealing.

[Douglas C.]

Hi. I am having the windshield in my 69 convertible replaced, and I notice there is what I would call a 3M type black dum dum globbed between the bottom pillars and the top rear of the fender. I suspect this is to seal water from the pillar bottom / inside of the car, and maybe direct water to the drains at the cowl corners.

It looks original and kind of a sloppy job. Can someone confirm this and explain / show pictures of what it should look like? Thanks.

Re: Windshield pillar post bottom sealing.

Hi Douglas,
I found something similar on my 71.
It appears to me that's it's the same material or quite similar to the Thiokol sealer used to set the windshield.
It looks like it was 'pumped' into place while soft and was formed by the shape of the cavity it was in.
You can see the cut marks I made removing it. It's very firm now, but still flexible. If I asked my wife what it was she'd say "rubber".
I hope this helps a bit.
Regards,
Alan
