You can search around at most hobby and home supply stores and find a rattle can that will match the color of the covering. After you spray it, you can put a clear of topflite lustercoat clear on it or nelsons hobby clear, which is water based. Some kryon paints, the laquer variety will be more fuel resistant. But if your good with filling and tuning your engine, raw fuel will barely reach the painted surface. Mainly it's just castor oil all over it by the end of the day. I guess I', going onto the fuse tonight maybe, I was working on the skybolt and had a good head of steam working on putting it together and I went to put in the cabanes and ,........yeah, they were missing from the kit, so it got put on hold real fast. I spent 3 hours digging around to see if dropped them in a crack somewhere. So I hear you like exotic materials? The fuse has 2 areas that need a reinforcement, you can use aircraft ply or,...carbonfiber, glass cloth or kevlar to reinforce the side doublers. The landing gear plate area needs real aircraft ply and tristock or just glass reinforcement around the internal structure. But all the weight added can be removed by opening up a few holes in the fuse sides and bottoms.
