JP,
I use Gorilla Glue because it's lighter.
I cut my sheeting 1/4" larger all the way around the wing, put the GG down on the skins and scrape as much off as I can get with a credit card. Put as much glue down as you need but it will mostly come off when you scrape it.
Then mine goes in a vacuum bag but you can use weight, just use a lot! The LE wraps around and actually bunches up but after it's dry I cut off the excess and then sand the LE down till I get to where the foam and skins make a good tight bond. Then I put a small cap strip, usually 1/8" or less because the vacuum bag does a good job at squeezing it down. Then I round it to match of course.
The stab photo shows the LE before shaping.
I use the sticky back sand paper on my glass top to sand the LE flat.
