I have done a few repairs and I usually put vacuum bagging film over them or sometimes just tape right over a small repair with plastic packing tape. There is almost no sanding to do when you do that. The only disadvantage I can see is that you wind up with resin filling the weave on the top instead of squeeging out the excess and later filling with micro or something lighter than pure resin.
