What can I do to avoid the scales to form a white milky type of outer layer after a few days of drying. I tanned my skin using true tan and mounted it on a manikin. As soon as I noticed that some scales were getting a little white I sprayed on some clear top coat matte to try and seal the scales before they peeled off. However some parts of the snake look awesome and others (tail area) are starting to look a little white again. I sprayed some more clear matte and it helped but I would like to know how to avoid this in the first place. Again, some parts of the snake look really nice but other scales have formed a white outer milky colored stuff. I tried taking it off with a needle but it seems that what remains doesn't have the detail as before. Should I have let it dry before adding the top coat matte. Is there something I can do as soon as I mount the snake to lock everything the way it is and then just let it dry on its own without this problem?
