Biltema wrap failed miserably as shown here.
This time I used another brand.  Actually 2 other brands as the first roll wasn't enough for the whole header. The Bronze wrap is Thermo-tec and the other wrap was called "Mines" but I doubt it has anything to do with the Mines tuning firm in Japland. I hope this is the last time I wrap this header as the fiberglass itches like crazy. Gloves didn't help.
