Guys, I call this wetting "P" shaped welting. I found a bunch in the trash during my all expense paid trip to Afghanistan. I found the vendor and they want $15 a foot for it. I have also found it locally in high heat orange rubber. I think there must be a cheaper source and in black, but maybe searching for it as "P" shaped welting would get more results. I will post some pics of what I had asap.
