Finally got around to doing the install a few minutes ago. Easy as pie...really...no problems whatsoever. Just watch their video a couple of times, read the instructions a couple of times, and you're good to go. Just make sure the lids are very clean and lint free, and do it in an area that is not cold or not too hot. I would NOT do this outside or in an open garage. I have a basement that stays relatively cool, even though it's hotter than Hades (some people call it Hell, but I call it Hades...mmmmmm) outside in Alabama today. I cleaned the tops with Griot's Spray Wash and a microfiber, then Windexed both with another clean microfiber. Got out my high intensity floor light so I could better see what I was doing. Mix up the solution in 24oz spray bottle of water, WASH YOUR HANDS to get rid of oils, wet the lid with solution, wet your hands with solution, unroll the film for whatever side you choose to do first (they are marked with Orange tape for the left, black for the right), wet the surface, make sure your fingers are still wet, peel off the film, wet down both sides, place on the lid and slide it around, into position. The film is cut so that the entire lid is covered, with the exceptions of a small part of each of the four corners, which is a radius cut and about 1/2" of material hangs over each side/end of the lid. Once in position, wet the rubber squeegee provided, wet the surface yet again, then hold in place with a thumb (that's a little tricky 'cause the stuff wants to slide around), then start about 3" from the front of the bag and stroke from back to front to anchor the piece. Wet it again. With a long, contiuous stroke, move the squeegee down the center of the bag, all the way to the back. Then get on one side of the lid and go from the center to the side all the way down the bag...repeat for the other side. Wet it again. Go over the entire bag again with firm strokes lengthwise, including the edges (not over the sides). Wet the provided microfiber cloth slightly (all wetting done with the solution) and roll the towel over each edge and down to remove solution/air. You have to work at this a bit to ensure all the edges are adhered to the side of the lid without bubbles. Then wet the whole thing again and go over it with the towel to remove excess and inspect your work to ensure there are no bubbles anywhere and that all edges are adhered. Repeat on the other bag. Took me about 30 minutes from start to finish.
Now let's just hope I didn't miss anything. It takes the stuff a couple of days to fully adhere, and they say there may be a slight haze here and there from moisture, but the film is breathable, so these will evaporate. I don't see any such places thus far.
Here's what it looks like putting it on, with the front tacked down and ready to squeegee the whole top:
