I went through and added the Static wicks to the right Rudder skin after all the stiffeners and the Top rib were attached.
The Top wick is in the flange of the Top rib and the second is 12 inches down from that point in accordance with the Dayton Granger RV-10 recommendations.
The Dayton Granger 1615 wicks are available from: http://search.skygeek.com/?vwcatalog=stylespilotshop&keywords=esd1&x=0&y=0
Dayton Granger placement for the RV-10 is available here: http://www.myrv10.com/tips/staticwicks/StaticWicks_RV10.jpg
Easy to get to with the squeezer
Not so easy - Used Back rivet plate and hammer and nail punch
