What grit paper do you guys like for removing light pitting? The kind of pitting that you find under surface rust, but it doesn't seem to be too deep. You almost can't see it really well straight on, but when you view the reflection at an angle, it stands out like a sore thumb.
Do you go lower than 220 grit?
For this type of (relatively light) pitting, how long do you generally expect to sand each side for before you're through it and moving on up the grits?
And this may seem like a dumb question, but you don't just sand at the pitted areas... you should remove steel as evenly as possible from the entire length of the blade, right?
And one last thing... the sandpaper is supposed to wear out very quickly, right? (I'm using 3M wet/dry paper from autozone).
