I sand the wood and glass to 220. You want to remove all the shiny part of the glass, it is a release agent used in the manufacturing process and no finish will stick to it very well.Mack is right, its not a tough finish but I have bows over 10 years old and have had no problems with dings or scratches.Also if you did ding it, its very easy to do a refinish. Thats not so easy with an epoxy finish.Apply the thinnest coat you can and let it dry completely. I put it in my bow oven at 100 f.for a couple hours.Then smooth with #000 steel wool. After about 4 coats switch to #0000 steel wool.If you want a non shiny finish, rub it out with #0000 steel wool till you like it and then wax it with good paste wax. Bob
