I've read several fancy ways to avoid the other great bugaboo of vac kits, sanding off
too much at thin spots when dressing down the mating surfaces,
but I just keep checking progress and shifting my grip around
on the part so I'm not always bearing down on the same place.
(Another thing: if you want detectable progress, use 100 grit
or 120, but nothing finer.)

messy but strong and I pull off the clinging adhesive with masking
tape when the sanding is finished. Again, keep shifting your pressure
points around and checking progress:
