Hi all Mine has given up the ghost, crumbled and collapsed. Tired of having bit's drop on me when I'm checking the oil or whatever, I've pulled the rementents off. It came off pretty easily actually, just a couple of bit's left to scrape, a job for when the weather gets a little warmer. Has anyone tried the SL shop version? http://www.theslshop.com/mercedes-benz-sl-r-129-under-bonnet-insulation-1296802025.html I can't imagine this item is much more from an MB dealer? Any other suppliers or generic solutions used? I'm guessing it'll provide heat and noise insulation, mine is only a 320 so under bonnet temperatures never get all that high, does leaving it off make much difference?
