Got a nice little heat shield for my head pipe from aliexpress. about $9 with shipping charges. It's a pretty sturdy little unit, and it even comes with a gasket-like set of washers to isolate the plastic from the metal and keep it from melting/burning.
I suspect this thing is going to melt since it just feels like regular plastic, but I will give it a go.
I've also been considering giving this larger fender a try for the front of my bike. The little one I have on there now looks ok, but doesn't offer a whole lot in rock and splash protection.
