Any smooth plastic bag material will do. You will know it when you see it. Authors note: This was cut off the end of a bag from Volare Products. I also keep this plastic in a “kit” of sorts for these repairs in a plastic case that I have purchased at a Dollar Tree Store. Look for a set of yellow screw drivers in a small black case that sells for a dollar. I take the screwdrivers out and use the case. To me, the case alone is worth a buck. In addition they’re great for holding modeling pins and other items as well.
