So my Honda City's underside plastic shield's retainer plastic CLIPS used to fall down time and again.
The plastic shield then used to drag along the road.
Replaced the plastic clips several times, but they always fell down, and along with it the shield.
This time I fixed it using nuts/bolts/washers instead of the clips.
Job well done and permanently.
Wonder why the manfacturer won't fix it with nuts/bolts instead of the pathetic clips? There is hardly any difference between their prices and they are cheap nevertheless.
