The newest tail for 'SPIRIT' was skinned entirely with polyester resin-soaked cardboard, temporarily T-pinned to an underlying clear-heart, red cedar wood skeleton, attached to a welded electric metal tubing ( EMT ) frame.
I did fiberglass, and then use polyester-based body filler on the 'outside' surface of the cardboard. Then primer and automotive top-coat.
When I become 'rich and famous' I'll graduate up to epoxy. It's far and away superior.
