There are two LNC4's, with body work and paint done by the same guy, one 
with static wicks– the other without.  Both have leading edge pitting after 
flying through rain.  The one without the wicks flew at about 210 KIAS 
through a brief level 2 rain shower and showed erosion of the leading edge 
on both the wings and the horizontal stab.  The worst of it were two pits 
about ½" across down to the carbon on the wing leading edge about 15' from 
the fuselage.  Most of the erosion was much smaller (1/8" in 
diameter).  All of the pits have a smooth surface.  The plane with the 
static wicks shows similar.

Any ideas as to cause or cure?
