Noted at Oshkosh as Fred did that most completed IV's have the squared off
elevator c/w horn, as this was the accepted method of finish.  In talking
with Carsten on an under-balance of my elevators,
(I had  balanced and closed the elevators per the manual) he recommended
sanding down and opening the end of the c/w area to allow additional lead to
be installed and then closing back up with a rounded finish.  I made a form
out of some plastic pipe to make a 2 bid cover that would be uniform in
shape, installed this piece over the newly balanced area, and then installed
a 2 bid over the cover lapping back onto the elevator c/w.  The result is
great looks and LOTS  of clearance between the stab and the c/w for ice.  An
additional benefit is when the elevator is deflected at all in flight the
air now will travel over a rounded surface.
    For the last 2 years I have talked to TKS on any developments on de-ice
for the IV.   I have seen the effectiveness of many de-ice systems and feel
the glycol drip works the best for my region and flying conditions.  I was
given the name of a builder developing the TKS on his IV and now can't find
his info.  Would appreciate any info relating to this system developed on
the IV.  Although I considered this option to be important before, events
over the last few days make it a "must consider" now.  Just spent the last 3
days assisting the Coast Guard and the CAP flying grids trying to find
friend and fellow pilot who went down at 4:00 AM while on an ILS  approach
to our airport.  The 10,000+ hour  cargo pilot reported moderate ice on his
de-ice equipped Travelair  8 miles from the marker, we found him about 5
miles farther up the localizer.  Needless to say the results were very
sobering.
   Any info on de-ice would be greatly appreciated.
