I live in corvallis, Oregon so there is a lot of rain...however I don't plan on taking my bike out in the rain much anyways. What kind of wax do you advise I use on my steel pista? (it's the grey frame/black lettering if you care). I'd like to use some sort of wax cause the bike gets water spots/smudgy if I just wipe it down with a wet rag. There was some gunk on there so I used rubbing alcohol to get it all cleaned up.
