it wont hurt more than already is : )
Well, as I've done on mines (link on my signature) and most of users with the bare aluminum frames.
Make sure you order or get some decals, from ebay or from a user here Gil_m (i think)
You can easily remove the old ones by applying heat from a hairdryer.
start with wet/dry sandpaper like grain 500 for the biggest scratches, then 1000, 1500 and 2000, 2500, the highest the most shiny it will look after. lots of elbow grease required lol.
I bought a set of wire brushes for some difficult access areas. Then got the frame soaped and cleaned to apply autosol.
Every now an then I have to give it a little polish, no big deal.
if you search you can find more info! I think there is a user who got famous for testing it first, WD I guess.
good luck! you'll get addicted to polishing things lol
