Fixing high spots in ski base

After skiing on an icy track I noticed that the wax had worn off my
bases quite differently on the two skis. On one ski there was a 6"
white area about 2'in front of the binding, while on the other ski
there was similar wear spot about 1' behind the back of the binding.
Obviously these are high spots that need to be removed. The ski has
been stone ground, and I'm told that that procedure does not address
this kind of issue. How does one go about removing places that are
pressure points on the bases of skis? Is there a website that
describes the procedure?

Is white base after skiing all the evidence you have for these being
high spots? How do you know the bases are just not absorbing wax in
these areas?

Everett,
Is there any chance these two spots could have been overheated with a
waxing iron? And therefore many of the pores in these areas of the
base are melted closed - so wax is not being absorbed adequately? If
that was the case ... and if the damage is not too deep, the skis could
be re-ground to remove these "burnt" spots.

Rather than being high spots these could be places where the base has
been damaged/sealed by using a too hot iron during waxes. Or the base
could just have come that way. Does anyone know if improper stone
grinding technique could cause the base to become sealed?

There are two likely culprits. First, the base could be burnt or
"sealed" by overheating with an iron or during the stone grind. This seals
the pores in the base and prevents wax absorption. You can metal scrape
these areas and you will be able to tell if it is burnt by the base being
harder in that region than on the rest of the base. If you get after it
with the metal scraper, you should be able to get down to fresh base and the
spots will go away with some waxing.

If it is not a burnt spot, then it is likely that you have "hot spots".
This probably has less to do with a high spot on the base and more to do
with the flex of the ski. There is not much you can do about that.
