Tested out the metallic ink-jet printer paper, more of a shimmer than a true metallic, but looks okay, maybe a little better than the Sharpie treatment. 18mm booster to 13mm sustainer. Stretched the booster fins a little. Thanks for the idea! Will need to figure out nose weight, would like to keep total sustainer weight as light as possible to allow it to be launched single stage, might need a removable nose weight for two-stage. Would probably look better with a shorter distance between the booster and sustainer, could have recessed the sustainer engine mount a little more, but not too shabby. the other technique is to simulate a metallic appearance using color shaded gradients from white to light gray, like on the R2-D2 droid paper template. This makes a metallic glare from a certain point of view... I almost think that color gradient technique looks just as good as either the metallic Sharpie or this shimmer paper, and you can just print that on regular white paper with better results when printing out multi-color artwork.
