Dirty handrims... why?

[ckhouri]

just spray paint it or paint it with some polyurethane... works great.
you might need to do it a few times a year. its a 15 minute jobbie, dries quickly, is transparent... and does not give any burning feeling when breaking.
dont use the water based one...

love the plastidip product, but will not work for something that involves rubbing. the layer will just come off....

I remain unconvinced of why exactly this is happening. Obviously it was nearish this time last year when my handrims were doing this. It's been very intermittent. Sometimes it's really bad and sometimes there is no problem, I can push for miles without blacking my hands. From maybe July to December I could push 5 or 10 miles at work (indoors on flat surfaces) every day without a significant amount of blacking (although I probably washed my hands 3 or 4 times over the course of the day when I take a piss. Lately I can't go 300 feet without one of my hands getting visibly dirty. Which is another thing that I find really weird, it's just one wheel. My wheels rotate all the time because every time I get in or out of the car they end up on the opposite side (by chance, this just happens in the routine I developed of loading and unloading the chair). The side that gets my hand dirty is a little shinier than the other, but I also can't think why.

In retrospect it seems to be dry climates/times of the year when things get bad - winter, or trips to the desert.

I should just quit my whining and spray some paint of the rims, but it's weird to me that it will go away for months and months at a time, then come back unpredictably and only affect one wheel.

Aluminum oxidation is a grey/black powder. It could also be the metal itself. Raw aluminum is very, very soft. Dry enough hands could scour it a bit. Some soaps/cleaners also chemically react with aluminum and create a blackish powdery residue (which is technically a type of oxidation, I think.)

Did you prep the rim any?

I'm sure there's some of the original clearcoat in places on the rim, so I feel like I might need to sand it down a little before I spray it.

I'd give it a quick rub with some steel wool before spraying lacquer.

I once tried the Plastidip spray on my rims. It didn't last long. Began to peel and shred off. Ended up removing all of it and, just use the hand rims as they originally came on the chair

Wonder if any of the Flex Seal products would work better. They have tape (4 & 8 inches wide), spray, and liquid. http://www.flexsealproducts.com/

I've been running natural fit push rims for a couple of years now and it seems like the coating doesn't wear off of them like the Tilite rims. Haven't had black hands since I started using them. You can find them used on this site in the for sale section or on Ebay for a reasonable price.

I've had the same problem myself. My solution has been to wear full fingered bicycle gloves whenever I'm out and about.
