I disliked the factory body side moulding on the wagon so I decided to take a run at removing it. I used a heat gun set on low (approx 200 degrees Fahrenheit) and a plastic scraper. I heated up the trim and used the plastic scraper to get under both the moulding and the black adhesive. Once I got the end lifted I ditched the scraper and just pullled on the trim while heating the exposed back side of the trim. I was stunned how easily it peeled right off. Done in 15 minutes with only a 40 year old dirt outline of where the trim used to be. I took some Turtle Wax bug and tar remover, sprayed it on the outline, let it sit for 5 minutes and wiped it off with a rag. You’d have to look very closely to see that the trim was ever there at all.
