If you're not in a hurry, the old construction/finishing methods still work fine. If you do a doped finish, you can be guaranteed it ain't gonna peel off like all the Chinese wrinklecote that comes with ARF's, and people will gaze in wonder at how flexible and free your cloth or figure-8 laced hinges are.

Dope is relatively expensive, but materials like silk (from Dharma Trading) and Dave Brown's Skyloft are pretty cheap, with the net out the door price of a job being comparable to plastics, or a little less even.
