Spray painting would make the job go much faster than adhesive foil.

But before you spray all 50, do one test piece with a fairly heavy coat 
of paint.  Most (not all) spray paints on the market attack acrylic 
plastic and make it "craze".  Fine hair-line cracks develop - sometimes 
right away, other times after a few days.
