Can anyone help with this one?
Couple of years back I had a leak on one of my AC lines, it dumped the AC coolant along the chassis rail under the engine and a lot of it went behind that plastic sheet they use to protect the crumple zone on the front chassis (below the engine mounts) the AC Coolant had a green dye in it so now the plastic film looks crap.

It is, or should be a clear sticky back plastic, but there is also a lot of heat in that area so I want to make sure I get the correct plastic film.

I don't think there is a part number for it? So anyone have experience of what to replace it with?

Thanks
