The Original Hard As Hull is made with acrylic polymers. The Hard As Hull has a gloss finish is great for general applications. The Penetrator is a thinner version and it is about the closest thing I ever found to the old Griff’s head cement. Penetrator is specially formulated to soak in and lock in materials. It works well with coating dry fly wings. Both Original and Penetrator come with applicator brushes. The thinner works with both. All HAH products are packed in glass bottles.
