This Plastidip might not be so environmentally friendly (I think), but it’s a great rubber coating for any of your DIY projects that might require more stability and clean look. You can see an example over here of plastified origami.
Plasti Dip sounds like a great way to “mold” any objects you might want to incorporate with your future DIY projects.
Multi-purpose air dry, synthetic rubber coating that can be easily applied by spraying, brushing or dipping. Plasti Dip resists moisture, acids, abrasion, corrosion, skidding/slipping, and provides a comfortable, controlled grip. It remains flexible, stretchy and will not become brittle or crack in extreme weather conditions
