I used the tech spec tank grip. It has like 6 pieces that go around the tank where you thighs touch the sides and 1 big piece for the tank. Think it looks rather well too. Thought about the tank slapper but decided against it.
No, that stuff is all flat as a pancake and stiff. That would be very easy. I am speaking of the 3M material that goes on the top surfaces and wraps both around the edges and down the sides of the bags AT THE SAME TIME. Take a flat piece of paper and try and bend it around a basketball, you end up with too much material. Same problem. I talked to the guy on the phone and watched the videos endlessly and followed the procedure as closely as I possibly could. I suppose if I did it 100x I may have better luck, but I only have one bike. I looked at yours, you have 3 pieces on each side, what protects the surface where your belt bucklet or coat zipper rubs?
I am seriously considering just buying some packing tape. Same concept, petroleum based glue, cut each piece down to fit and wet it down enough on the surface of the bag and on both sides of the tape with the baby oil/water mix, bang, done.
