I wonder if I got some old ones of these shipped to me ? I put them on the bottom of my saddle bags to keep muffler heat off my bags. After less than 1 day of riding, they were falling off. Both sides, even the side not near the mufflers. And the sticky stuff actually stayed on the bags, and the fiberglass stuff peeled off. I don't understand it, but they didn't work good for me.
I purchased this to prevent excessive heat buildup in my exhaust-side aluminum pannier. As promised, it significantly reduced the temperature in the case. The only problem is that the adhesive started peeling away from the case during the first use. Since I do long distance riding in all types of weather/temperatures, this clearly was not going to make the grade. This product is a good concept, but is worthless if it can't remain secure during normal application/use. Don't buy this!
