Depends how bad they are, if your going to try and do it without removing the wing then a dent puller, or hammer it out from behind if you can get at it.
If your going to need to respray, drill a little hole and put a self tapping screw in, pull the dent out with the screw then take it out and fill the hole, sand it and respray. Due to where it is, and where the seams are, you will probally get away with a can of paint and just masking off the area after the seam, the seam helps to cover the difference in the paint colours.
