all right, couldnt find good info anywhere else, and I know the 3d guys must know something. I realize translucent covering is lighter, but by how much? what brand is lightest? My favourite is ultracoat, but my guess is it is heavy . I was almost thinking along the lines of adhesive-less covering and balsarite etc...
note... this is for a laser 3d
if you have any other good "jenny craig" tips post em here... lets try to make a resource out of this thread as I couldnt find the info elsewhere on the site. Im going to go to some hobby sites and research claimed weights for various coverings.
