After reading the threads that were devoted to what everyone is using to protect their radiators, I went with the Nomex option. I have to say it was a breeze to work with and install. Cuts easily with a razor knife and is flexible. Radiator fan install kit adds to the ease of the installation. If you have a Backdraft, all you have to do to access the back of the radiator is undo the bottom fan bolts and the fan will swing away. I painted it a flat silver using high heat paint.
