To ArtisanCraft, Anyone ever had problems with acrylic primer on polymer clay? I recently bought a Vallejo white surface primer and covered half of the sculpture, thinking that it will make the paint stick more. Did the procedure right, but it scratches off with a light scratch of my finger nail. It's already been 5 days curing but it still has no good news. The coat was not too thick nor too thin, adding a layer of paint over it didn't help. I did clean the figurine first with alcohol. Any advice on this? Does this primer take more than 5 days to be ready? As for now, painting without the primer is stronger than with the primer. If
