winglet lower extensions?

["Schweitzer, Bill" <bill.schweitzer@TANDEM.com>]

Alan, 
Here's something that has been in the back of my mind and your informative
message today gives a perfect opportunity to ask it.

I notice that your prebuilt wings do not have the lower extension, I admit I
haven't dived into the specific plans yet to see if I have to build them.
Do you do that because the toe-in is correct and you don't need extensions?

I built an s-curved gusset out of 3/8" foam for the rudder cable as it
leaves the fuselage and heads through mid-air into the gear bulkhead.  I cut
a few circles in it to save an ounce.  A 3/16" groove on the top holds the
nylaflow and a little micro.  One layer of bid over the top holds everything
solid.

What's the reflective material, the foam or the paint?
