Priming laser printed models

I recently bought a color laser printer, and am very satisfied with its print quality, the colors come out nicely and small detail is reproduced distinctly.

However, the first laser printed paper model I tried to build was awful. The printing was fragile and easily scratched or flaked off the page, and the pigment layer broke off along folds.

I spray painted the sheets with Krylon clear spray, the printing held up much better, the pigment did not flake off the paper, but the surface of the paper was left slightly glossy and did not accept glue or water colour paints. (I was able to glue up the model using organic solvent based tube glue. White glue would not stick to the varnished side of the paper.)

Then I tried Aleen's Matte Decoupage. I brushed on a thin coat over the laser printed parts using a broad soft brush. I let the page dry, sandwiched between two weighted sheets of Corian to keep the sheets from curling. The Laser print pigment did not flake or scratch off when handled, was resistant to cracking at folds, and the coated sheets glued easily with white glue, CA and contact cements and could be over painted with water based paints :).

I used Aleens, but Modge Podge or Deco Art would probably work just as well.
