Technical Removing old hardened rubber seals

I’m currently working on a 28 Ford open car and the rubber seal below the windshield has hardened like old plastic. When trying to remove it, it just breaks off in chips. It is a “T” shaped rubber extrusion that goes into a channel in the windshield frame. How do you guys remove this old rubber from the channel?

Hammer, chisel, utility knife, dynamite. Or all of the above. You just have to chip away at it usually.... Ain't old cars fun?

That's the way I do it. HRP

 

warm with a heat gun.

 

Thank you guys, I’ll try all of the above, and give updates

Thank you for the help. I started by heating up the area and that made the rubber soft again. Then it moved a little easier and I’ve been taking it out piece by piece with a screwdriver and the help of soapy water

If you think it might help to get the rubber softened up a bit, you might try slathering on a generous layer of cream type hand cleaner (like the old GoJo or D&L hand cleaners) and let it soak in for a day or two. The solvents in it will soak into the rubber and some of the cleaners have a bit of lanolin in them which will keep things from drying out. I don't think the citrus based or gritty pumice cleaners will work as well.
