The wings should be quite firm on the spar... you don't want to any play in them at all... so if you are going to give them a sand then proceed with caution... ie: sand a little and check fit a lot.
If you over sand them and the wing becomes sloppy you will end up with movement that will cause fatigue, and eventually failure... If the wing does end up moving around on the spar it is likely to give you some issues during flight that would not be pleasant.
