Hello,
I am trying to create an overhead transparency gel effect, like in the most recent BMW commercial:
http://www.topspeed.com/cars/car-news/video-bmw-s-story-of-3-commercial-ar9...
The way the transparency gets peeled off, it's fantastic. I am messing around with blending modes and opacity, along with CC Page Turn effect, but I just can't seem to get it right,
I also can't seem to find any conversations or tutorials on how to do this, does anyone have any suggestions?
Thanks!

You have the right idea... you'll just have to keep messing with it... some cases might call for overlay.. and others the color transfer mode... maybe even soft light.

Hard to say what would look best considering I'm not looking at your footage.

Final thing I will say is that desaturating or treating your underlying footage will make you color overlays stand out more.

The higher they fly... the much.

color dodge with luma mattes and saturation mattes. I really like that commercial.

I did a really quick test to see what would I do. Here's a list:
CC Page Turn- obviously you go that too. I used this twice.
One for the top layer (multiply) that shows both Front and Back (77% opacity with grey bluish paper)and one for a precomp (dark grey layer with a mask that leaves only the feathered edges of the layer to show and a grey bluish layer at 30% opacity)- this Page Turn shows only on the back of the page- 16% opacity. This will give you a difference of texture and transparency for the back of the transparency gel and will better define the edges.
Then I used a blur, Hue/Saturation to lower the saturation for the reduced sharpness and colors from the image below and Light Sweep (on top- animated to match the turn)- all on adjustment layers with animated masks that match the Page Turn.
Parented all to a Null to be able to move the "gel" around.

Try the Liquify effect under "Distort". Sounds like you have the right base.

Rrecomposed your page turned layer and add a force motion blur effect to it. It could add some realism.
