Aluminum parts on stock blaster?

Yes, I'm looking at what I can polish without needing to prevent rust from plaguing me weekly. I've done a lot of reading and research about the whole polishing process. I've done a lot of reading trying to find out what parts are aluminum as well. I'm coming up empty-handed.

Just looking for quick, one word replies, unless the clutch and brake levers are the ONLY aluminum parts on the blaster...a little help please. Thank you.
 
The case, cylinder, front hubs, head, carb, brake caliper. I would just do the magnet test, if it don't stick it's aluminum.
 
Thanks for the responses fellas. I'll get to work on polishing my tires now...haha.

I've been following along as Mr305 polishes his parts and it made me want to give it a try.
 
Once I get the materials and get started, I'll post up the before and after pics. The only polishing I've done so far, is using the Mother's polish on my levers...just to clean 'em up.
