280z Hatch Glass / Seal removal

So I have a lot of rust bubbling along the bottom of the hatch seal. I don't think I need to remove the glass but I need to remove the seal (chrome center with rubber on both sides) in order to treat the rust. Does anbody have a link to instruction on removing and reinstalling the seal? I assume I probably need a new one which is a shame, the current seal looks in great shape. Thanks for any direction.

The hatch glass sits in a channel in that "seal". It's a complex bit of rubber that holds the glass, fits around a flange on the hatch to keep the glass in place while sealing the top of the hatch from the elements. The "chrome center" is stainless steel strips that hold the weatherstrip in shape so it doesn't pull away from the corners.

Normally it's easiest to cut the existing weatherstrip to get it out of the hatch and use a new one to re-install the glass with the new weatherstrip. If the existing weatherstrip is still very pliable, you could remove it by prying it off the hatch flange from the bottom side of the hatch and pushing it (and the glass) up. It's normally not worth the effort it requires though.

These come from an era where the glass is not glued in like todays auto's. Maybe there's a YouTube video that shows how 1970's automotive glass is installed...

TBH I'd take it to an auto glass expert who is used to dealing with this old style of seals to remove/reinstall the glass. It is very easy to shatter the glass if too much pressure is put anywhere.

I had my front and back glass redone at a classic auto glass shop for $200. Well worth the money as new glass for our cars is not cheap.

I'm sure you can have them remove the glass and hold it while you work on the rust.

If the rubber is pliable still and you know what you're doing you can pull the rubber and glass as a unit and get away with it. Like someone else says, too much pressure and your have a shattered window. Much safer for you to cut the rubber to remove the glass and replace the rubber gasket outright. I usually carry the rubber in stock. If you want some you'll have to contact me direct via my e-mail or call me. Regular price is 69.95 but mention to me that you use zcar.com and the price is lowered to 64.95. Another word of wisdom, cut the chrome trim out with a razor blade first and under no circumstances ever pry on it even a little bit. If you tweak it you'll render it unusable, don't even look at it cross eyed. Z man of Washington
