If you put the 2 half's of the wing together and they fit flush then you will need to sand the V brace a small amount till the wing fits flush. Then use masking tape around the edges of the wing and epoxy. after the wing is together then wipe off the extra then pull the masking tape and it can save you a lot of clean up. we have found that epoxy has a habit of setting before you are ready no matter what the time limit on the bottle says.
