Im taking my car over to the body shop in 2 weeks to have them fix a slightly decent size hole in my car about a baseball width. What id like to know is, how to remove the chrome wheel well flanges. I tried with a screwdriver with all my might but to know avale. Do I have to just take a grinder at this point and grind the screws off??? I want to clean up the surface rust on the 1/4 panel flanges. I am getting ready to put this car away for the winter, its almost november, its getting painted in the spring. I already tried penetrant on the screws they wont budge.
