Default Upper windshield frame putty?

Inside the channels of the upper part of the windshield frame is a putty type substance that completely filled the channels prior to me removing it.

What was it? Presumably it is to waterproof the windshield frame and T-top bar.

What can I replace it with? Is there a problem with sealing all the seems with silicone once I'm finished POR-15ing the windshield frame/bird cage?

Thanks!

I used 3M Strip Calk. It comes in black or white and does a nice job of sealing everything up.

I used black ribbon caulk from NAPA - about $15 and enough to do a number of cars - use on top and sides of windshield and even bottom if required. Can also be used on t-top bar where there are open places.

Silicone will cause enormous problems for you - it should never be used on metal parts of a car exposed to moisture / weather.

The original sealers were either seam sealer or (in the area you mentioned) Butyl caulk, depending on the application. In areas where you might think Silicone, Urethane is THE choice.

Why is this? What does sealing with silicone create?

Silicone is acidic and will attack the metal over time. As mentioned urethane is the choice over silicone. Our metal building has the same concerns.

And it is extremely aggressive. Tends to cause very deep rust that travels much faster than just water or moisture alone. Very nasty!
