I had a GTS bug shield for my fox body, way back when, and it was contoured to the hood but had a little but of a lip on it on it's edge. It did a good job deflecting debris AND you could still get soap and water under it. Agree though, it *looks* like it's just sticks to that nose like a trim piece.More than likely it just keeps insects, etc. off the finish and stones, etc., from nicking the paint.
It seems too flush to the fascia to provide any deflections.
