I have not burnt my self on Bonnies engine bits, however i seem to drop jackets, cloths and rags on the pipes on a regular basis. Melted my mesh jacket on the right side pipe, and only last week melted one of my synthetic cleaning clothes on the left pipe. It now has the strangest texture on it. When i get past the ^%$ ^&^%$# &^%$^&* pipes attitude I will get down with some cleaners and elbow grease and put it right. But at the moment im still in the "argh screw it' mood.
