I’ve got a couple of broadhead targets that are showing their age. Plan on injecting spray foam in the soft areas to help em last a little longer. Has anyone sprayed/ painted the outside with one of the rubberized paints? Thinking it might form a “skin” that would help keep the foam slivers inside where they’re needed. Concerned the rubber may friction weld to the arrows. Hoping someone may be able to provide some insight. Thanks
