It would appear neither shiraz or underpants is part of a formula for good results. Plasticene dam under LWA4 had moved, leaving a blob of flox over the rear face. Outside the bolt area, but just stupid.
Pop off W18, (rather easily), and note a hideous black mark in the pocket underneath. What could it be??? Remove flox blobs without dinging up the metal or paint, then notice another hideous black mark on the other side. The drain!!! I had forgotten about it in eagerness to install the metal. Without popping off the W18 I would never have noticed until there was a Shear Web over W18!!! That's it, I'm never working in my underpants again!
Reamed out drains
Trued up the wing foam with Dave B brand Giant Alloy Ruler (tm) and 5min floxed to upper rear jigs.
Removed the nose jigs from 1/2/3/4
