Soft, squidgy and bendy.


Recommended Posts

In the olden days, car manufacturers, when they ran wiring thru the cars bulkhead from the engine bay to the cabin, either used rubber grommets or occasionally a soft, squidgy and bendy black mastic.  This stuff always remained soft, squidgy and bendy. I have had many potential uses for it over the years but don’t know what it is called.  I could use some right now to seal off some outside lights.  Anyone know what it’s called ?

Dum-dum I think Steve. What olden days of motoring were these then? 

Of course, there is a far greater variety of superior sealers on the market now for sealing outside - from silicone based compounds of all colours, to over-paintable acrylic sealers. 

Kind regards,

Gareth.

Good point, Gareth. I did intend to be more specific, but I’m not entirely sure. My company car was a Ford Granada Ghia at the time, so does that make it the late seventies perhaps.  Certainly the name Dum Dum does seem familiar, so I’ll try that.

I do remember just how useful the stuff was.  It did not stick to the fingers and remained infinitely malleable at all times.

Thanks for the assist.  Cheers.
