So, for the glass install I roughed up the pond armor were the glass would be laying and took a tack rag to it to clean up the dust. Then I put a thick bead of silicone in a "Z" pattern so when the glass was placed it would spread to cover the entire contact area. After the glass was in place, I took and put a bead along the edge to the pond armor as well. It took 2 tubes of silicone per window.Did you use double seam silicone for the front glass? Did the silicone adhere to pond armor well? So nice!
