Good way to repair cracking rubber?

Was just looking for suggestions on repairing gashed rubber. Any suggestions welcome. Was thinking krazy glue? Not sure how well that would hold up though to dropping them. Pictures below:

Re: Good way to repair cracking rubber?

Perfunctory googling suggests that vulcanizing fluid is the way to go, then maybe a patch over it. A lot of places say "regular" glues (contact cements and the like) won't hold up as well for a tire repair, and I'd think we want these to be as durable as possible. OTOH, vulcanization is irreversible, so you may be up **** creek if it doesn't work as intended. But krazy glue may do some weird stuff to the rubber as well.

Best of luck!

Re: Good way to repair cracking rubber?

I've never heard of vulcanizing glue, but we have used rubber cement (get the extra strength version if you can) with decent results for small gashes. Anything larger than that or where the rubber cracks, I would trash the bumper and get a new one, we haven't found anything for that. We have some Mavrik bumpers 30+ yrs old that are cracking.

Let us know what you decide to use.

I agree. Let us know what you use and how well it works. These boards are full of home gym DIYers and repair info is pretty valuable.

What kind of silicone? I'd be a bit nervous about adhesion, as well as differences in thermal expansion causing it to separate again. But it might work very well.

Re: Good way to repair cracking rubber?

Is it dry rotted?
Dry rotted rubber is just gonna get worse.
Glue can not hold it together if it is deteriorating.

Re: Good way to repair cracking rubber?

Should have been more specific. Its not cracking, its more gashed, looks like its from a razor blade. Its a new bumper, came in the mail like that.
