When you order your decals you will get to chose what kind of material you want; be sure to chose the one that is designed to be clearcoated. I found the "wet install" pretty easy; that is, you wet the frame with slightly soapy water (dish soap) and apply the decal over that. The soapy film allows the decal to slide around enough that you can get its location just right. Be sure to let it dry an extra special long time, though; they won't be fully hardened until all that water is gone, which will take at least several days, perhaps a couple weeks depending on conditions. Then clearcoat.
