So many ways of getting a smooth back that doesn't require the burden of a bondo filling..StrykerP wrote: What I do with my Sinew Backed bows:
I mix dry clay powder with titebond 3 to make a clay paste that isn’t extremely thick. I cover the entire back of the bow with the paste to fill in all of the groves, crevices, etc.. after it dries for a week, I’ll sand down the back of the bow until all of the clay is gone, except what is filling the crevices, etc... pretty much making the back nice and flat and smooth. I’ll then apply rawhide or snake skins. I then apply 3-5 coats of polyurethane for outside wood decks. That poly is designed to be durable to withstand all the traffic, flexibility of the wood, and pretection from the elements.
