Hear how Bob M. from Indiana used his saved time:

I've always loved the sets and costumes from Disney's version of Jules Verne's "20,000 Leagues Under The Sea" and I decided that GI Joe needed a cool new dive suit.
I used a vintage GI Joe Deep Dea Diver suit I got in a trade as a starting point, it had a nice lived-in look (it is tea-colored from years of hard diving adventure.) I got the belt and knife and the base for the collar and helmet from a Rapid Deployment Force flying outfit- these fit nice and tight on cc joes head and have a chin guard attatched to the helmet that you can build up on with sculpy. The 12" Nascar figures have a perfect helmet to use as a base for sculpting the dive helmet- a chin guard really helps. I used sculpy to build up the helmet. I used an extruder tool similar to a big hypodermic syringe to make long cylinders of clay and then wrapped them around the base helmet doubling the strips where it needed to be thicker. Using uniform coils helped keep the depth of the sculpy uniform. I blended the coils and added details. The cowling is made from flat pieces that I rolled out from more cylinders (uniform mass to start from) and just joined at the corners by smoothing. bake it and then you can sand it and whittle on it if need be. I used copper paint from a craft store that has a lot of metal in the paint to make it seem more metal-ly when it is dried, I should have put a gloss clear coat on it but I am too impatient to ever do stuff like that. The lens was cut from a clear spherical ornament I got at Michaels craft store, a gumball machine prize-holder would work too. The top vent is from a bubble blowing barbie mermaid. the tubes are from zoid models. the brass thingy over the cowling is made from stacking flat black and brass beads from a bead store together, the real metal makes the whole thing look better IMO. The tanks were made from a trashed set of joe tanks with thin copper and paint added. The top of the backpack is covered with thin craft metal I found a long time ago, I haven't seen any for sale since but it might be available at train or RC hobby stores. The gun is an Action Man space rifle with some details added and a little copper paint. The spair air tank is from the Classic Collection airborne jumper. Cotswold Collectibles sells repro dive suits, beat up vintage suits might be better.
