First, you should do this on a warm/hot day in direct sunlight. The heat will help soften the adhesive, and the direct light will help you see the adhesive residue. Start by placing a paper towel under edge of the hatch. Spray the lettering with Goo Gone. Let it soak for 30 minutes. It will not damage the paint or clear coat. Use a scraping tool to remove the plastic letters. Apply more Goo Gone and let it soak for 15 minutes. Use the scraper to remove the adhesive. Clean the area with Windex, then apply car wax or another protecting car product.
