The Dremel will melt plastic quickly, because of its high RPM.  Thank =
goodness I tested on the hidden part of a tail...

  I just hit 'em with the buffing wheel. Never really worried about what =
compound I used. They come out looking like new. It only takes a second =
or two. I'd be leary of using the dremel - use a buffing wheel that can =
cover the entire key width. You can remove a pretty deep gouge in just a =
few seconds. Go with a slow speed. Don't do it too much because you can =
melt the plastic pretty quick.

    Hello list
    I don't know if this subject has been covered. A client has this Yam =
U1 which suffered a broken key-top. The broken part successfully glued =
in place but the whole area needs repolishing.The surface is lightly =
scratched - enough to visibly and tactilely make one aware that all is =
not what it ought to be. Any ideas on this? Dremel buffing mop? Any =
special gunge required?=20
