Rudder Closeout Tip??

[Tony Renshaw <renshaw@ozemail.com.au>]

Gidday,
For the rudder closeout I am stuck wondering whether I should do the layup
of the bid on plastic, or the conventional way. I feel for later down the
track I should practice the plastic technique, however I worry about the
second ply prohibiting the first ply, and itself, from contouring to the
reducing radius of the closeout toward the tip? 
Any Tips would be appreciated before I launch!
