The following procedure is for anodizing aluminum parts. Anodizing will protect the aluminum parts by making the surface much harder than natural aluminum. Aluminum oxide is grown out of the surface during anodizing and then becomes aluminum hydrate that is extremely hard. The porous nature of the anodized layer allows the product to be dyed any color that is required.

I've had a go and it really is as easy as he states.
I used ordinary black dylon dyes for my parts but they didnt take the colour very well.
Came out a golden dark bronze, this may have been the type of extruded aluminium I used.

Anodizing can be done at home but if you want the cool colors you will have to deal with some pretty toxic, carcinogenic chemicals. I have a PDF booklet on how to do if if anyone would like (drop me a PM and I'll send you a copy). Remember though that anodising is a super thin coating so you would have to have the part polished or otherwise prepared before treatment or you will just see a pretty color over scratches. The two reasons above are why most shy away from the process -- easier to just paint it.

P.S. Anodising does not make the part any stronger structurally.
