i cut most of the guard off and then slid a screw driver inbetween each spot weld and grab plyers, gripped the 1cm ish width edges of metal and peeling it back. but i wouldnt recomend it becasue it left MASSIVE contortions and bends on the outside of the tray. another way i heard about is an air chisel hooked up to a compressor. but dont rely on my advice hahahaha .. someone else should post a "normal, easier way" up....
