I've had some made up for some time that I was going to send to you. The best luck I've had was with using the satin finished adhesive vinyl with a gloss clear vinyl overlay. The clear adds some UV protection. It stands up much better than the paper decals with clear vinyl. The paper had a tendency to wick up moisture. But even though I've only had my air cleaner on the car for a few months, I can already tell that there is a slight loss of color already. - And I had used the better pigment ink too. Send me a pm with your address and I'll send the ones I have to you to look at. You may want to try them out on a surface that does not have delicate paint on it so they can be removed without risking damage. Ideally I think I'd still want a competent vinyl graphic sign shop to make some for me. It's nice to have these for 'test' decals though.
