My understanding is that the purpose of the mesh is to prevent the strike by
draining the pre strike static accumulation, much like a lightning rod on a
house will prevent the lightning strike. As someone else commented, that got
them certified. Beyond that - I don't know. It has been way too many years
since I worked with high voltage systems.

How many strikes can the mesh layer take before you throw away the plastic
airplane?
