I have been experimentin' with various films. Monocoat which is used mostly in t' RC aircraft world for skin o' wings and such adheres t' cardboard and plastic really well and add sheer strength too. Avast! Monocoat comes in a whole bunch o' colors and runs about 15 bucks a roll. One roll is enough t' cover a lot o' mid power rockets. Self adhesive films are also fairly easy t' work with and give good finish results. I have built a number o' boost rockets and boost gliders and use t' shiny chrome on t' bottoms o' t' wings with very little weight gain. Avast, me proud beauty! $3 bucks for a 6x36" strip. Ya scallywag! I've attached an example o' t' results. Aye aye! T' fins, couplers, upper airframe and nose cone were covered with film.
