I have painted whole cars and rebuilt engines. I have also applied brushed finishes to small aluminum parts (valve covers and the like).

For me painting an entire car, including all the prep, was a lot easier.

I'm not saying that the OP doesn't have the skills to pull it off. Just that it's going to be an excruciating job to do a proper brushed finish on an entire Kirkham right. Know what you're getting into and then if you still feel comfortable, go for it and report your results. You just might teach all of us a lesson or three.
