Seven years ago I scratchbuilt a UFO model that required a high-gloss metallic sheen. I bought some Alclad, followed instructions, but the project didn't come out nearly as nice as I'd heard it would, so I ditched Alclad for a while. Today, on a KC-135 Stratotanker kit, I hit the engine cowls with some Alclad Polished Aluminum, and man did it turn out nice!
I'm sorry, Alclad. I'll never doubt you again. LOL
I'll post up some pics after I have all the masking tape off.
