Hi, My first post as a Nikonian member. Enjoyed reading other posts and site info for past few months. I have a question I'm hoping some can help with.
I'm looking at purchasing a used Nikon 17-55 f/2.8 lens. Condition looks near perfect, except the focal length adjustment ring rubber shows oxidation/whiteness. Works fine, just doesn't look all that great to me.
Done some searching and found someone recommending 303 Aerospace Protectant to make the rubber look brand new, without being greasy. Anyone have experience with this? Any other suggestions? I searched for purchasing a replacement ring, but looks like Nikon doesn't sell this particular part(maybe they wish to fix something like this themselves?).

Be careful using silicon based protectants around glass. With heat they outgas and will produce a thin film which is very difficult to permanently remove. Remember detailing your dashboard with Armorall and spending the next three months getting the residue off the inside of the windshield!!

Hold off on that. The reason is that Nikon uses double-sided adhesive tape to secure the ring to the barrel. My 16-85mm was just returned from Nikon Service for a related problem. I cleaned off the zoom ring with rubbing alcohol.
This dislodged the ring. I gently pulled it off and cleaned off the muck on the barrel with more ISO alcohol. The zoom assembly came undone. Nikon fixed it for free, but the lesson is that high tech solvents shouldn't be used on this equipment.
I worked at 2 airlines and my shop is full of those wonderful space-age lubricants, grease and cleaners. All with the MIL-SPEC rating. They work like nothing else, but are cancer-causing and require handling with care.
That doesn't fix your problem, however. If you go to an authorized Nikon repairman (not Nikon itself), they shouldn't charge too much to do a fix the right way. Nikon won't sell the parts to consumers. Approved techs will have them, though.
I use 303 all the time on a lot of things, including everything on the interior of a car including leather, and love it. Unlike Armorall it doesn't dry out things like tires. From their web site:
"303 contains no petrochemicals, silicone oils or petroleum distillates"
I almost literally hose down the interior of my car a couple times a year, and work it into leather, vinyl, plastics, etc. The only downside I've seen over 10 years of doing this is that it is very hard to clean off of glass and LCD screens (e.g. a GPS); no harm, just doesn't come off easily.
That said, I've never tried it on a lens rubber. But I'd absolutely try it before I did something like Armorall.
My older lenses have some whitish look that I probably should clean, but I've just put up with it rather than risk messing it up. If you do it, let us know how it goes (and after a few weeks if it held up)?
BY THE WAY... 303 makes a lot of products (good products), so be sure you look for "303 Aerospace Protectant". In particular a lot of people (and store clerks) confuse it with "303 Fabric Guard" which is a waterproofer. That is NOT good stuff to use on anything but certain fabrics, and does contain solvants.
I have use 303 for years on cars, guitars and camera gear. Must keep off of the glass and out of the works a little goes a very long way. Clean your hands well and don't touch items until completely dry.
I bought an old Nikkor 28-80mm f/3.3-5.6G lens recently & that had a white deposit on the zoom ring. I carefully removed it and put it on a tapered tumbler while I cleaned it with an old toothbrush, washing up liquid & water. I rinsed & dried it off & put it back on & it looked like new.
I would absolutely recommend Protectant 303, based on my experience of using the product for years. I recommend wetting a small cloth with the product and wiping it on the lens area to be protected, allow to penetrate for a bit, then wipe with a dry, soft cloth. I would absolutely avoid Armorall for this application.
your rings are suffering from oxidation and the sun or air. I use rubber rejuvenator (Rogersol #184 product 12-01840-1p). This is used to clean, and restore rubber press rollers. This is what you should do, get a little 1 oz bottle and go to the local printer and ask for a little rubber rejuvenator. He wiil give you some. You can buy a 1 gal jug but it will be unnecessary since you will use very little to brush on your ring. These protectorants are silicone based products which leave a coating on the rubber. Put these on your tires and not on your camera.
