Well, the board that is used to properly fair is called a torture board.

Long for and aft sweeps with the board chine to chine are needed to get things flat. You can do the process with a notched trowel and sand less and fill in at the end.

If you think you are done, you can spraypaint it with a dustcoat.

Putting a fluorescent lightbulb vertically will help.

I have some pictures of me using carbon black instead of spraypaint, but I hated it.

Adding to what fallguy posted, use a can of Krylon fast drying spray paint and shake it over the bottom or sides as you spray it to get dots. It will dry quickly and then take as long as torture board as you can handle 3-4' and sand the bottom this will show you the lows that are left to fill on the bottom.
