Here's the ending of my wavy trailing edge skin story.
The ailerons are finished and though one had significant waves in its skin prior
to installing the aex wedge, they both came out fine. I did use the proseal
approach. Also the one with the waves still has a couple of minor wide spots
where the waviness wasn't completely removed but one would have to be really
studying it to notice.
One has no warp and the other about a 1/8" rise. I think the warp began with
the installation of the counterbalance because my 1/8 aileron had with a slight
warp after I installed it. I figured I could get that out by weighing things
down during subsequent process. Oh, well.

The best way for me to do the trailing edges was to use a piece of 2" X 3" angle
iron 1/4" thick,
mounted into my building table. Use the holes in the trailing edge as your drill
guide and drill every
other hole into the 3" side of your angle. Drill at a comparable angle to the finished
skins.
When you are finally ready to rivet the trailing edge, install every other rivet,
tape them into place,
turn it over and calico the empty holes to the 3" back riveting bar. (The 2" X
3" angle you just drilled)
Then do the standard back riveting. After every other hole is riveted, remove the
clecoes and back rivet
the remaining holes. Be careful not to place any of the factory rivet heads over
any of the holes drilled
into the bar, when you back rivet the remaining rivets.
This procedure made a very flat trailing edge for me.
