I used Testors Decal Paper on my inkjet printer... did a great job.  However, I watched in horror as the decal disintegrated before my eyes when I dipped it in water.  Then I went back and read the instructions... I needed to use Testors Decal Bonder Spray after printing and letting the ink dry sufficiently. Got both at Hobby Lobby, two trips and two 50% off coupons!  Would have been nice if HL kept them close to each other on the shelf, I guess.
