I just did mine yesterday, didn't need much to glue up the trailing edge, I mixed it in 2 batches since I have B1/2 and didn't use much more than an ounce if that. I sealed the wedge to the right skin clecoed to an aluminum angle I drilled up, let it cure, then did the left as I "zipped it up" like the plans say. The final product is straight as an arrow. Wasn't as bad as I expected.
