Question about sealing airdry clay

i have used paperclay to try to make a BJD before. I wouldn't advise using it. It is not strong enough, and breaks so easily. It is also VERY dusty and seems to easily decompose. I have not used any other air dry clays, but other people on this board use LaDoll. It is hard to find, and I am too lazy to order it from some international website. I use super sculpy....

If you must use the paperclay, I would say you could go to the art supply store and get some spray-on acrylic fixativ, or even get some sandable primer.

 

If you're going to cast it, the super sampler kit from smooth on comes with a spray on sealer for porus stuff. :3

 

I'm actually under the impression that you could just use a spray paint on it. I wouldn't recommend a clear one, since it might not allow you to see where your project is flawed. But, when I did my first doll (which wasn't a bjd, but this still applies), I wanted the surface to be really smooth, but I was using bisque. It's really tough to get that stuff smooth if you don't sand before firing. I sanded a bit after it was fired, and then I used a few coats of white spray paint. It made a really good seal to it, and since paperclay is more porous, it would probably adhere to it really great.
