I had the local sign guy copy a set of spares I had. They are "layered" in three separate pieces in ultra thin vinyl and are BEST suited to be clear coated over. I have done a couple of tanks now and no one has protested the decals. I clear coat over all the decals on all the tanks I do, because the decals never come off and at the end of each race season a quick soapy sand, and a couple of new coats of clear and she's good to go for another year.
Cheers,
K
