Yes its very similar to maskol joe , its a latex fluid that dries very rubbery , its main drawback is its impossible to clean out of a brush and it stinks like fish ! It was always used in schools back in the day over here for sticking paper etc but we mainly used to make great big rubbery balls with it or paint it on your hands and peel it off once dried like some horror movie !Looks good Tony. Is this stuff like a Maskol-type fluid? I did a Macchi Saetta years ago and used blobs of Blutac. Looked like it had the pox.
