I start with a 3-M metal finishing pad to smooth the surface then work down to 400 grit paper. Then it's the buffer and compound until the aluminum starts to shine. Keep working and you'll end up with parts that closely resemble chrome at far less cost than having them plated.
Due to EPA regulations you might have trouble finding a chrome plating shop. Most of them have gone out of business and those that are still around have gone away from the old 'triple plating' (copper, nickle, chrome) that they used to do. What's out there today is a single layer chrome job that doesn't look or last like the real stuff used to.
Aluminum castings can be polished very nicely with a little work.
The shop that chromed my forks used copper as a base. I messed around with the cover I took off when I added the pull starter. I went down to 1500 grit wet sand paper and finished it off with extremely fine steel wool. I could shave using that thing as a mirror. But it was a LOT of work! Plus it had a flat surface.
Bike Berry had the best selection of chromed parts. But they didn't have what I wanted. I'll take some picture of the parts and send them in for a quote and see what comes back. I'll probably end up polishing them myself then spray a clear coat on them though.
