I have been using Rineharts smooth fish fill for my cheeks,head junction,finbutts and tail junction. It is so hard that my dremel bit starts to smoke sometimes when I am grinding out the eye sockets. So what I am wondering is if Rineharts regular fish fill will work for what I am doing with it? Is it softer than the smooth fish fill? I have used Jim Hall mache and liked it but I do not want to order it from where I got because I do not have anything else to order with it and shipping is horrible for just one item.
