Might that also be the stuff around the outside that turns white in the sun and constantly requires cleaning LOLGo sit in your tj and count the plastic pieces that you find. Report back with what you find. This might surprise you it may not. News flash tho...the tj has a ton of hard plastic all inside too lol. That door panel you rest your arm on when you drive...it’s hard plastic. This might open your eyes it might not, but the tj has a ton of plastic also.
