As title, about to look on EBay/Amazon etc but would be great to not go through the learning curve of buying inferior rubbish before discovering the best options. The "Shore hardness" needs to be around medium soft as a rough guide. I have inherited some on recent bike, but about to strip and powdercoat.
I'm not quite sure what you want but my understanding is you want something to stop movement/rattling of panniers and top box On my sports bikes i have SW Motech soft panniers to protect the paintwork i use some black rubberised mesh which is sold in many places as non-slip cupboard and drawer liners. I found that a small piece folde over and placed on the rack of my top box stops all movement of the top box (I also discovered later that custom paint sprayers use it to make avery good imitation of carbon fibre)
I’ve previously used flooring protection pads for furniture with some success Bought then cut to size to suit your needs Stops rattles and protects painted surfaces.
