when I changed rubbers, I took off the rubber but surface of the bat ( around the edge) came out , although it is not much, I am not sure it is good for using it, if I repair it with wood filler and sand it, would it be ok ?
Or use epoxy, it is very durable. Wood filler becomes brittle.
some wood has came out with the old rubber, can not glue them back.
I use wood filler to restore minor splintering and clips/chips for club members with good results so far.
