[Elecraft] KAT500 question

It seems like I've heard someone suggest that spray-on car wax does a
good job of making the ladder line real slippery.  I haven't tried it
yet, but I have two ladderline pieces on my NVIS loop. Twenty seven
feet of feed line and a ten foot stub at the opposite corner that
detune a bit in the rain.  However when the loop needs to be
re-matched I just hit the straight key here and the KAT500 finds a
match that works.  However I seldom run less than 100 watts.
