I have some pitting and corrosion on the alloy covers on the virago,
and want to buy a dremel type tool to help with getting them clean and
shinier. I read that stainless steel wire wool can be useful in
removing the corrosion, but what sort of attachment or tool would I
use in the dremel for this?

I sure as hell wouldn't use a Dremel tool with any kind of attachment.

Buy a cheap Chinese bench grinder for about $40~$50 USD and some cloth
polishing wheels and an assortment of sticks of jeweler's rouge and do the
job right.

Remove the covers and degrease them and polish them out just like the
professionals at the chrome plating shop would do.

Then, when you're done polishing, spray clear urethane to keep the covers
from
corroding due to road salt.

Echo Al, Dremel way to fast and not enough tork. Maybe use a 3/8"
variable speed drill with a wool buffing wheel and jewelers rouge.

You actually want to go slow, like ~800 RPM tops and wet to keep the
temp down. You can *MELT* the alloy, wavy look to it, by generating a
hot spot with a dry high speed set up.
