Hello, just a simple question for the experts here in this forum.
I made something with DAS air drying clay and with Hobbycraft (UK) Air-Drying Clay. I want to be able to sell it, and so it needs to be waterproof. I am going to paint it – assuming acrylics are most suitable?
But does it need a protective varnish after acrylic paint to make it waterproof? Acrylic paint usually dries up pretty plasticy so perhaps it is enough?
If it needs a varnish, what do I use? I’ve spotted Fimo varnish, will that do? Do I need a special clay-varnish?
Many thanks in advance! really appreciated.
