Scott,

  Put a couple of grains from the 120, 240 and 500 grit next
to the scratch and use your 10X magnifier. Which ones are larger than your scratch?

  Unless you got a scratch from one of your tiles, I'll bet a
couple extra wets with your 500 will fix it. Now you know not to let the
wet dry out, and I'll bet you won't do it again ;-)

Sigh. I was pretty much done with 500 grit on my 12 1/2" -- and quite
pleased with how well it was going. As the mirror dried I saw a 1/2"
long scratch appear. It looked like a surface scuff but after anotehr wet
it showed its true nature - craters the size of elephants (well at 10X
anyway) in a line. I am not a good judge of sizes, but these look larger
than the 500 can easily get rid of. I know I need to drop back a grit size
and get rid of this horrible thing, but is there a good way to estimate
whether I need to go all the way back to 120, or if 240 suffice?=20
