Hey, Andy,
Yeap, that is what my AC friend gave me. It is ALMOST as thick as the difference between the oleo and the main strut. Just a TAD thinner. I just do not care for how it looks on an old test strut. Now, my AC friend popped by for a beer earlier. He took one look and said "Ahhhhhh, I have just what you need." He popped out to the truck and came back with what appears to be a mylar tape in shiny silver by 3M. MUCH thinner. I need to get some wax paper to adhere it to for cutting it down to size, but that may be the cat's meow. I'll let you all know how it works out.
