I own a 2020 Impreza, and damaged the plastic cover for the undercarriage; now it's hanging off partly and scraping on the ground. I'm in the process of trying to find how I'm going to replace it, but I want to take off the plastic so it doesn't scrape against the ground until it can get replaced. What would I need, tool wise, and how would I go about taking it off? I'm not very experienced with car maintenance and repairs, so I am not sure if I will be able to do it myself but I am just wondering what the process would be. Thank you!
