I am actually finishing a 5.5" Polecat Redstone right now. It comes with just the United States decals for the body, no capsule decals at all. I have ordered more detailed decals through Mark @ Stickershock. The capsule itself is smooth and void of any detail. I am using an Atomic City 1/12 scale Redstone capsule to provide even more detail. The Atomic city skin fits pretty well over the fiberglass polecat capsule with only a little modification. It provides all the detail you could want along with a very detailed escape tower and every waterslide decal to fit all known mercury capsule markings. The polecat kit is great and uses great quality materials. I will try and post some pictures soon.
Good luck with your project, you will love the Polecat kit
