REFLECTOR: Water in the ducts & firewall integrity

[Keith Hallsten]

Jeff,

I installed the fiberfrax and SS sheet on the firewall today, and I intend
to seal all around the perimeter of the SS with RTV (or something similar)
to try to keep all liquids from contaminating the fiberfrax.

I'm not a big fan of the duct arrangement in the Velocity, both from the
wash water/rainwater/fuel leak point of view as well as the serious
compromise to the integrity of the firewall.  I think I'll put in some small
drains, but I'll also make a serious attempt to seal up the ducts at the
firewall, around the tubes and wire bundles.  It remains to be seen how much
success I'll have with that effort!

Keith Hallsten, XLFG

OK...I have read all the posts about water in the ducts.....There is a 
BIG question I have: Perhaps y'all read my posts about filling my tanks 
with green water and finding leaks all through my floor boards.......if 
water collects in your ducts it could /*as easily */collect in the foam 
of *YOUR* floor.......WHAT happens when it FREEZES?   Delamination? I 
would expect so.....
  I put heat lamps on my floor boards for a WEEK and tonight drilled 
test holes and found WATER.(I finally found the source of my leak was a 
vent line I had to put in to the right tank as a retrofit for the newer 
sump tank and vent system...).....I finally drilled a HUNDRED holes 
through the fuselage to let water out and it WAS coming out...of a LOT 
of the holes...now I plan on letting the lights shine for some time 
before sealing all of the holes AND putting holes in the ducts where I 
can....I think it would be a GREAT idea to paint the area under your 
ducts (before assembly) AND put drains in SEVERAL spots BEFORE glassing 
the ducts in!!!!  Does this make anyone else sweat a little?     J
