I am attempting to put up some shutters. However, in the area where the hinges need to go there are quite a few screw holes. In some cases they are really close(ie a few mm away) to where the hinges should go. Consequently, I can't screw the hinges in in this area as the holesa re too big. Is there some kind of product I can use to fill the holes so that I can then redrill new holes to take the shutters.
