The scales can be fixed. If you want to take the little chips out, get some black epoxy die. Mix up a small ammount of 10 min epoxy. A quick set keeps it from sagging. Put some wax paper behind the scales along with something flat like a paint stirrer from the hardware store. Then you can use a toothpick or sliver of wood to dabble epoxy into the bug bights to fill them. Then sand it lightly with some 400 grit where the epoxy was applied. That will get it even with the scales. Then give the scales a light sanding with some high grit paper, 800-2000 to clean and smooth them out. You can wipe the scales down or soak them in some neatsfoot oil to recondition them. Then give them a buff with some white compound to shine them back up like new.
