no no no dont do it ,it will give you a terrible hull the only way i can see you could use the ribs is either cover them with balsa!! or use card board.then coat the card with pva and water let it dry completely then try the releas agent and glass over it.tape will never work.far better than tape you could use brown paper and pva and water .do about 4 layers let it dry it will shrink enough to tighten up and not sag.i used brown paper to cover this plane and it drys hard and tight also.excuse the dust lol.[img][/img]
