During the contouring, filling and sanding bit (oh no not that topic again!) a
powerful light shone along the surface being worked on can be useful in
revealing the high/low spots.
It helps if the light used is concentrated into a beam.
In this respect, has anyone tried using a laser beam, eg one of those relatively
cheap laser pointers available for presentations etc.? The straightness and
colour of the light may be more effective. I expect that subdued background
lighting would also be needed.
Anyone tried it?
