Soft Material?

Hey there, I've been customizing 7" scale figures for about a month and a half now and I've been using Mighty Putty and Apoxie Sculpt for them. I'd like to get a soft material, something rubbery and pliable, to do things like jackets and hair with. Does anyone have any suggestions? I'd prefer something that I could get locally, but if that isn't an option I'll go online.

Thanks

Maybe these guys have something?

Hot glue supposedly works great for hair and facial hair . I believe I read somewhere where the bionic commando figure's hair was originally cast in hot glue and then a mold was cast from that. I could be wrong.

Super Glue. Its hard and rough, but if it were added to the soft material I bet it would be pretty hard and good. Only thing I can think off without causing serious risk to the sleeve.

To work on things like coats and hair, I'd like to obtain a malleable, rubbery, soft material. concrete driveway (https://wellingtonconcretedriveways.co.nz/)
