    Rubber Hood Rejuvenation

    I picked up a set of older brake levers today- the gum hoods are intact- and overall, they're in good shape- but the rubber in places appears to have dried out.

    In the past, when I've gotten levers with old hoods that weren't in good shape- I'd just cut 'em off and squeeze the levers into some of the Cane Creek hoods- but these are in good enough shape that I'd like to not replace these.

    For things like printer rollers, the rubber 'rejuvenator' actually breaks down the rubber- to make it more tacky. I'd like to add moisture to the dried area of rubber.

    Any ideas?

    303 Aerospace Protectant. I first learned of it years ago on the Classic Rendezvous mailing list. It provides UV protection for rubber.

    Once they start breaking down, I think it's pretty much close to impossible to "rejuvenate" them as they are organic materials that break down internally. You might be able to coax back some moisture on to the surface of the hoods, but once they darken, crack deep inside and tear at the edges, it's pretty much a losing battle. Our only hope will be more people deciding to manufacture reproductions with hopefully better materials that will make them last much longer (silicone?).

    I always think of hoods as a consumable item like tires or brake pads.

    Agree. I wish Hudz would make repro grips for all of the older shifters; there are so many of them still in service.

    Seriously. Try ArmorAll Cleaner to remove the crud and ArmorAll Protectant after that. I've brought some hoods and other stuff back from the dead this way.

    I don't know if you've used it or just looked it up, but this is in the usage instructions.

    Rubber Renue works by causing the rubber cells of belts, platens and rollers to swell. This swelling allows dirt, particles, and contaminants to be easily wiped away. Once the Rubber Renue has completely evaporated, the rubber cells shrink back to normal and the surface is refreshed and ready for service.

    I've heard bad things about Armor All doing good things when it's fresh- but worse after it dries/wears off.
    If you've used it with good results on hoods- that's better than an anonymous "I heard..."

    I haven't heard anything bad about those products, so I'll do a little research. I will say that my own personal experiences have been very positive though.

    I have had good results with this also. Used it to bring some Campag hoods back to life. Wrapped the hoods in paper towel that was pretty well soaked and left them in a plastic bag for a month. Not by plan really, I went out of town on business that long. It will not fix totally dry, but it can help with those not so far gone. I am still riding those hoods. Shoot them with 303 from time to time. I will say I did not have such good results with some Mafac hoods.

    Sounds worth a try to me.
    On your hoods

    Seriously, I'd just get some new ones, if available, or use them as is. A top dressing is possible but I doubt you can actually "add moisture" to dried rubber. This subject has been discussed a lot on this and other forums and so far no great ideas that actually work have been proffered, AFAIK. 303 sounds the best.
