My kit had a short-shot ventral fin; the plastic did not fully fill the entire mold, losing the tip. I sliced the ragged edge straight, then superglued a thin piece of stock styrene. Once the joint had hardened, a little sanding produced the following results.
The wings were finally glued on. Care was taken to ensure the wings dried at the correct 3-degree anhedral droop.
Due to the kit design, a large part of the join will need to be eliminated (marked in red below).
You can see the rivet lines indicating the true panel breakdown of the actual wing.
