Matt J,
They have been on my hives for a year. Neverwet dries to hard and "permanent" film, once painted you never have to refinish again. There isn't any periodic cleaning, repainting or replacement needed, that's the beauty of the system and plus its inexpensive. As per the video the coated flanges are stapled on the 3/4' riser of the bottom board, the flange stays attached to the bottom board, the hive body only contacts the uncoated side of the flange. You may want to watch the video again, all of this is explained in the video. Our Lowes and Home Depot stopped carrying Neverwet, I have purchased it from Amazon. I recently found it at a Tractor Supply Store on clearance for $5.00 a kit, needless to say I bought 6 kits.
