What grit of sandpaper for the bottom?

[HPjunkie]

Ive seen some posts that recommend a certain grit of sandpaper to rough up the bottom for an extra mph or so. Is it 320 or 400 or 600 or what? I have the boat off of the trailer and getting ready for the mess now. Thanks Greg

Speed coat the bottom man.

One thing to add...speedcoating doesn't require any sanding.
