I built an eps (not superfused) quad that now has a ding about 18’’ from the tail on the bottom. Customer wanted the quad to have 5 fins and while drilling I found water. Can water travel that far in eps or should I suspect something under the tail pad. thanks but its not water from the compressor as it failed the taste test. (seawater). Can water travel 15 inches if the board is stored upright??? Customer fessed up to have surfed a long session before noticing the ding.I supply aluminum insulation tape on delivery day, just wish theyd use it if needed. thanks for any input
