Oxidised aluminium acts as a protective coating and isn't a corrosive issue. Aluminium alloys often have enhanced corrosion resistance.

If you go raw, after polishing (if you want to) simply clear coat it. It's just paint without pigment.

Gives it a nice shine and takes the scratches a little instead of the frame.

I know its not corrosive, thats why I said it would "oxidise if untreated"

and if its being clear coated you will have to use a specific lacquer or it will not key and eventually flake off.

Aluminum wont corrode, well not to the point of actually damaging the material.

A VERY thin layer oxidises actually forming like a protective crust over the bare metal. That's how anodising works... Its a sped up corrosion but they introduce a dye which actually colours the oxidised layer.

Plus once its polished you can get it powder coated clear which will stick to the bare aluminum.

Here's my mates effort.

Nitromors, sandpaper and a lot of time, oh and a dremel tool for the nooks and crannies.
I don't think he would do it again!

His frame is raw, no clearcoat just decals.
