Today, I removed the muffler and heat shield for servicing (don't ask why). This is the first time that I have removed the heat shield since I installed it (about 1.5 years ago). This is the double layered heat shield that I spoke of earlier. After inspecting the two layers, I thought I would report to you all their conditions. The main stainless sheet (immediately beside the muffler and touching in a couple of places) had two spots that really showed heat penetration. In fact, after some mild 240 grit sanding, I still could not completely remove the spots. The second sheet (nearest to the belts) showed only regular weathering. In fact, just by looking at it, it seems like it had only been left out in a couple of rain storms. After a quick cleanup, it was as good as new.
