PC-7 is the only stuff that I’ve seen work and last for fixing steering wheels. Open up all the cracks you can find with a disk and go in angles to try to undercut so you can get sort of a dovetail lock of the epoxy once you spread it in the groove. That epoxy is like tar so once you get it sort of done, you can wet a rubber glove with acetone and smooth it out as the final step. There’s a ton of working time, so no reason to hurry with this stuff.
