Re:poor man's decal

I need a full-color, durable decal to label a front panel.The panel is ~8x17".  I'm only looking for prototype quantities(someone else can deal with production quantities and "revisedartwork").I think I can just color print the image, 1:1, laminate itand use a spray adhesive to affix it to the actual panel.This would be a win as it would be easy to replace when accessto the hidden fasteners is required thereby buggering thedecal.  (imagine doing same with a "real" decal and hopingto get such a large item off "intact" soas to leave a virginsurface for a replacement!)I only have hot laminating capability (but could access coldif there was an overwhelming reason to do so -- e.g., single-sidedlamination?).I can use a 7mil film to stand up to the mechanical abuses thatwill be encountered.No idea how the colors in the print would fare, over time.Nor if the film would yellow or become brittle with age.But, both seem like they are likely far enough in the futurethat it would be easy to dismiss them, now.Anything else to consider?
