So the crack in my winder just got a whole lot bigger. There is some rust
around the edges, which I should probably address in the process.

How have you all managed this process?

Im not going to install the glass myself, but perhaps a week before I am
ready to have it installed by the local shop, I could manually remove my
current glass so I can start to use some sort of anti-rust materials on it
to get it ready?

Don't want to reinvent the wheel, so im just looking for any tips you might
have when you have addressed this issue yourself.

Thanks!
Chris.
