What's the non setting black gunge pros use to seal between old type car windscreens with a rubber mounting and the body? It's not silicone based. I've tried two motor factors and only been offered silicone based stuff.
Years ago one of our customers used to manufacture the stuff and applicator machines, they were called "Gurit-Essex" but have now been bought by Dow, but could give you a starting point ...
I believe this is the system
Probably black butyl putty.
I've used such stuff. I've a feeling it was called Dum Dum ........ ????????
I suspect it the same as the stuff called black tack in our industry.
BT use it as a non-setting cable sealant. Horrible stuff really, leaves marks, but is good flexable non-setting sealant.
Are you thinking of black Bostik adhesive? I think that it does set fairly hard. It's very messy stuff, but I believe that petrol (or paraffin) is the solvent to use.

The stuff they use these days grabs well initially so a vertical screen would hold, but never goes hard. Excess rubs off glass or hands easily with a dry cloth.
It's clever stuff.
I've ordered up the 3M type after a recommendation in uk.cars. maintenance.
