What should I use to fill in rubber?

So I have a new drive shaft carrier bearing for my B3. I would like to use something to fill in the void in the rubber. I have heard people mention windshield urothane to fill up engine and trans mounts, but dont know which to use. Obviously I want somthing that isnt going to become hard when it cures. I would need somthing that would become stiff, yet stay plyable. Anyone BTDT and can tell me what they used?

I've done 3 UrSpig center support bearings with 3M window weld, no issues with any so far.

That's exactly what I needed to know. Any idea how long it took for it to cure? That is quite the void to fill. Thanks

Wear gloves, it won't come off anything.
You're welcome, good luck and post some pics when finished.

you know, that title is a bit suggestive. you just have to plunge in and see what's the reference.

I thought about that after I posted it.
Then I figured I should let it go and see what came of it. Low and behold, I go the answer I was looking for first

Any major issues doing this to an older but still intact bearing? Maybe even while still installed in the car?
I would think that as long as you support the shaft a bit so it isnt "sagging" while it dries, it might work out?
I know.. I'm being lazy...

I did mine on my coupe with RTV. I'll have to check it out while she's in storage to see how it is holding up.

I would imagine that would work fine. I had thought about doing it with mine. I would say as long as it is centered in the housing like it should be, it would be fine.

RTV was mentioned by Elaw over on MG. I was thinking that RTV might be a little too soft though. Would be nice to see how one that has been done with it is holdign up though.
