I realize it's a little late to suggest this, but I'll go ahead and make it anyway. For any part of a "can" that would be normally have bare aluminum visible you could (have) apply(ied) some Trim MonoKote (or aluminum foil tape) to further the illusion that the rocket is made from beer cans. I used that trick on my Deep Space OFFl build, and it gave it a really nice flashing effect as the rocket came down under parachute. In thinking about it some more, there's still time to apply it to the underside of the nosecone. [EDIT] Now I'm thinking of one with a "Duct Tape" finish... A "Red Green" rocket.
