I've seen a kit by Maier for a heat tile that said it is good for 400 degrees constant or 500 degrees intermittent.
There is also a kit called Lava Mat. Here are it's specs Specifications:
Brand: Heatshield Products
Mfg Part: 770001
Color: Bronze
Finish: Carbon Fiber Look
Material: Crushed Volcanic Rock
Size: 12" x 24"
Temperature Rating: 1200F Continuous (1800F Intermittent)
Thickness: 0.007"
Is this overkill? I just don't want the new rear fender to melt by the kick starter like I see on so many other ATC's. What have you used that worked?
