I used Chrome Ultracote. I love the stuff. Shrinks great but yes .. it will show underlying imperfections so you have to prepare the surface youre covering. Seems very strong and sticks well to the wood and to itself.

Im building a Ikon n West PT-22. Gonna do the chrome fuse thing like the real plane. Wing and tail feathers will be easy to see if the chrome becomes invisible .... hopefully. Worried about radio interference though with antenna routed inside the plane.
