Fiberglassing A Cardboard Jet Pack?



Fiberglassing A Cardboard Jetpack?

I started making my Stubby jet pack for my Jango costume because frankly, it just costs too much for a kit for me. I have made the whole thing out of cardboard and masking tape but I want to fiberglass over it to make it strong and smooth. Just wondering, would this work? Or should I just do paper mache?
dude you got pictures of that jet pack? I would be interested in seeing it.

i went with paper-mache, up untill the other day when the wind caught it knocked it on the ground and shattered the nosecone, but the papermache held so i have revamped the nose so i can use multiple warheads instead of 1 should be finished by the end of the month if it doesnt get to much hotter here in sin city, will try to post pics when its done

The resin used in Fiberglass contains acetone, it would eat the tape, and the whole thing could just come apart and get all messy. Um I'm going out on a limb here (It's a crazy idea!) but you could try to paint on some elmers glue on to create a barrier, then cover the thing in newspaper, and alternate between layers of glue and news paper until the thing is good and stiff, then just spray the thing down with a coat or two of polyurathane to keep the glue from melting from mosture......Just a suggestion.

Ok I got the thing fiberglassed but now what? Its all bumpy and fiber-like, how do I make it smooth and shiney? I'd imagine sanding would just make it fuzzy fibers...

You could try painting on layers of FG resin & then sand those until smooth which would be time consuming, add weight & cost OR use a skim coat of bondo which will also add weight. I can't think of any other way to fix this.

you can gelcoat it, pick up the stuff at a marine boat store. ITs what they do to make boats nice and smooth.
