If you are talking epoxy drips, try a large but fine tooth metal file. When it got clog, brush it with a brass brush parallel to the teeth to unclog. you can also use a dremel with grinding stone to flatten those drips before sanding; but be very careful and go slow.

: I've been working on sanding all the bumps, drips, and other imperfections
: off my two Pygmys, and man is it ever going S...L...O...W... .

: (Again, lesson to new builders: scrape off those drips while green! you'll
: regret it otherwise!)

: To exacerbate the problem (I love that word), my sandpaper seems to get worn
: out very rapidly. I'll put a new quarter-sheet in my palm sander, and
: it'll last for maybe one square foot of sanding, if even that.

: It's just generic multipurpose stuff (not garnet though, which I think I
: heard is quite soft), 120 grit. It doesn't tell me what material the
: abrasive is made out of.

: Is there a different type of paper I should be using instead? perhaps
: aluminum oxide, as I read in the old "scary sharp" posts?
