Black putty used on the speed nuts for the GFX…
Where can I get that black/dark gray putty sealer that GM used on the speed nuts that hold the GFX on? Mine are all dried out.

Plumbers putty is different composition and cream colored. NOT Butyl rubber.
I just bought below on Amazon, and it is just like the 3M Brand, i bought previously (like 20+ years ago)!

Thanks. I have some of that windshield ribbon sealer, a whole box actually, so this is good news.
