Can someone tell me how to fix cracked and peeling/splintered veneer on an exterior front door? The door is so old, they don't even make that size door anymore....it is a size 28 instead of the standard 34 -36" width. Replacing the door and installing it would cost us roughly $1700 because we would have to special order it. Can anyone tell me if I can just spackle and sand it, prime it and then paint it? We really don't want to spend the money on a new door, and we are thinking of moving soon, so we need to do it soon. Thanks!
