Brushed Aluminum Hump

Has anyone tried brushing the aluminum hump on the 9T to match the tank?

I think it's possible to get close using fine sand paper and WD40, but wanted to check with you gents before attempting.

I'm about to put a 22ple coat on both the tank and the hump but would like to get the hump close to the tank's brushed finish before I do.

I'm no expert on aluminum finishes, but my guess would be that a fine steel wool would probably be better at producing the brushed aluminum finish.

It appears as though BMW has beat us to the punch and will be coming out with a brush aluminum seat hump, based on some photo's another forum member has posted from his trip to the Intermot show. It looks as if it might be clear coated (like the tank) as well, which would help keep it protected from scratching. The current seat hump scratches so easily. I just bought one, but wish I would've waited for this one, if in fact, BMW will be rolling it out.

Also, loving the new dual gauges that are going to be on the R9T "Racer" (shown in the link above). I've asked the dealership is these will be compatible on older R9T's and was told, they don't have that info yet; until the bike rolls out and the parts catalog is updated. We shall see - I hope so.

Having watched a few youtube videos I came to the conclusion I'd only be able to make it look good on a flat piece of metal. The curves of the hump would make it impossible to get consistent brushes in the same direction.

I'm planning on buying the brushed one in the new year.

The new one is hand brushed so I can't see why you wouldn't be able to do it? Buy a small piece of all and practice with various materials then have it clear coated.

A bench grinder with a wire wheel or a drill with a wire wheel would do it easily. My greater concern would be with the existing finish. It seems like it has to have some coating (anodized, perhaps) or it would tarnish. Bare aluminum tarnishes like crazy. You could clear coat it afterwards probably.
