Re: Fairing Board
Posted by Dave Houser on May 26, 2004
If you use a fairing board you will have reflections with smoother lines. ROS will leave subtle dips that give wavy reflections. It is all cosmetics.
I use a 1/4" lauan plywood 4-1/4" x 22" fairing board with wood block handles at each end with 80 grit sandpaper for most of my sanding. Both pieces of an 8-1/2" X 11" inch sheet of paper cut in half lengthwise completely cover the board without waste. I also found a 1/8" lauan 2-13/16" (8-1/2" divided by 3) x 11" fairing board to be useful in hard curved areas.
I use 3M Super 77 spray adhesive to attach the sandpaper. A heat gun removes it quickly and cleanly.
With a little downward pressure while sanding the board will bend to match the existing contour and only sand off the highs. I use it after sanding off all of the shiny dimples in the lows of the weave with a ROS. It is also good for rounding the chines with smooth dip less curves.
