Technical OK window guys... Another Question

I notice on a lot of cars (especially newer ones) there's a black painted border around the outside edges of the glass. I'm guessing this is to hide the sealant from view when the windows are installed.
What kind of paint is this that sticks to glass? or should I just use some one shot and hope it sticks.

 

Chuck,I can't think of any enamel more suited for glass than one shot,the adhesion properties are second to none. HRP

 

I think it's called pinch weld primer.

Ditto on the pinch weld primer.

 

I'm not sure what the glass manufacturers use to put the black strip on the glass but I would agree that pinch weld primer would work

 

Its funny, but all the really good stuff is always 3M.... Thanks guys.
