why not experiment right?
600+ grit scotch brite (green) should do the job.
if it doesnt work out, lustre king the thing for 5 minutes.
you may want to look into one of these as well...
http://bowlingballreviews.com/ball.asp?ballid=2173PowerKoil 14 Coverstock, Inferno Core.
that could solve your problem, in the offseason i got one for $35 shipped.
it may be an avenue you want to look at.
