Ok another update on the metallic papers from papersandmore. Just did a test print on the cardstock - its very thick and was very much at the limits of my printer's capability (the paper path is U shaped - if you have a printer with a straight-through paper path it may work out better). It skipped a little each time the paper fed further, so every inch or so is a line of darker color and a slight shortening of the part. I used one of Cami's new '57 Chevy kits available at
www.ecardmodels.com, and the finish is spectacular. I might try to build this anyway. I'm certainly going to see how the spray seal works on it.
