Rust around windscreen

[Bitsa]

rt142 wagon and I'm ridding it of some rust around the windscreen that I only discovered when the chrome surround flew off while cruising in 5th one day. I know the windscreen is glued in, but, there's also some black rubber of some sort around the top of it.

I can take that out without fear of the windscreen falling out ???????

Youll need to remove the windscreen to fix it properly.
When its out youll probably find more hidden rust that will need to be fixed as well.

There really is no quick-fix that lasts... trust me, ive tried
