Troy - 1 Rizoma "reverse" bar end mirrors - get at PJ's - sorry don't have a link right now.
2 - covers - go to Ace - get "dads" paint stripper. Use tape to mask around case. Remove parts - shifter, brake pedal, etc. Apply dads with paint brush - clear coat will immediately bubble up - remove with damp sponge and then dry with towel - next wash with soapy water and rinse well. The dads is weak and WILL NOT remove hard anodising such as on shifter linkage and pedals. I did the covers on the bike. If there off your task WILL be easier.
Next work over the damage - use a course enough grade of sand paper to sand away the scratches - experiment here. If your scratches are deep you may need to work with a fine file or dremel tool and fine grinding wheel. Then use finer and finer grades expanding out from the damage to the entire part. I used 300 - then 400 - 600 - 800- 1200 - 1500 grits. Use the wet and dry variety and keep em plenty wet and rinse paper and parts often.
Next go to Home depot and get a few cotton buffing wheels, and some rouges - use only the final rouge or any type of cream aluminum polish such as wenols or blue magic if you have sanded with 1500 - the part will already be very smooth and shiney just need to brighten. Use course rouges and buffing wheels (on your electric drill) if you got tired of sanding and quit at say, the 800 grit :-D .
Keeping them polished - about every six months get a clean buffing wheel out and put on your electric drill - smooth aluminum polish all over the part - then buff to a brilliant shine - takes only a 1/2 minute or so and no hard rubbing and buffing by hand. Cleaning will depend on use and storage - mine bike is ridden about 12000 miles a year - but is not parked outside at work all day - and is stored in a garage. Ride only when caught in the rain. JCW
Should look like this when done.
