Hey be sure to test out the ink in your printer.

I had bought some cheap ink cartridges off ebay for 1/4 the cost that HP asked for theirs. The color photos I made from them faded in the house in a few months and one that I used as a cover on a note book left in the car out in day light faded blank in two days!!!

Take those decals and leave them in the sun to see how your ink holds up to the UV.

UV blockers in the clear coat help also.
