Good moldable flexable material

I know it's been awhile but I figure I would add two more cents. I made some flexible antennae for The Tick using an insulated solid copper wire as an armature, sugru, and then a mixture of clear epoxy and acrylic paint. I know, I know...everything about this goes against everything they said about mixing mediums in art school, however...bam! It works!...its been months since I primered it and it still hasn't done anything strange, like cracking or peeling, it solid and flexible...maybe a little too rigid, and it returns back to it's original shape, which wasn't exactly what I was going for, but it works. What was your solution and did it work out?

Thanks for checking in with results, glad that worked for you

I'd definitely need to paint it with acrylic paint

Sugru from Walmart

Could be a great choice in this case

Just keep in mind maybe Sugru can't be painted because it's silicone, and who knows if it will hold fine detail
