Removed the peel ply from the inside of the spar layup. Cut up the 1" foam for the spar. Wet floxed the WA parts into the DWA's and then the DWA's to the main spar in their respective locations. Slurry all foam and install. I simply clamped the DWA's down, and placed a light weight on each of the foam pcs. Be sure and keep the spar troughs clear and clean as they were already prepped with peel ply
