What makes a Jodo is the "Pain in the *** extra's", so when you're sat at your work bench at gone Midnight wondering why you just didn't stick with a Boba...
It's well worth going the extra mile when you see it all come together.
For the moulds I use Silicon from these folks Carbon Fibre Cloth, Epoxy Resin, Kevlar, Diolen, Equipment and Supplies for Advanced Composites - Easy Composites (after making a master copy from anything you can cobble together, card, wood whatever - then use a dental type Resin for the actual copies of Knee darts, gauntlet rocket's etc).
Decals looking good too. Glad Scott still had some.
The Weathering is such a personal thing, everyone has their own take on what's too much or not enough.
I'd recommend a light misting with a Black or Brown Rattle can with your kit laying on the floor, spraying down onto/over it, slowly layering it up to get that patina of Flu Whaka filth just right.
It's really coming together now mate, well done.
