I need to know what's the exact material of the E63/E64 LCI front bumper.
Generally BMW uses two types of plastic - Polypropylene or Polyurethane, which are indicated on the inside of the bumper with "PP" or "PUR" respectively. This is very important for painting and for work on the plastic (welding for example).
The E60 bumper is "PP".
Can anyone tell me what's the E63 bumper material? I don't have one in front of me but I need to know.
Thanks!
