If you have a crease dent in your car, there are a few things you can do to fix it. First, try to clean the area as best as possible. This will help remove any built-up dirt and debris that may have caused the crease. Next, use a plunger to push out any trapped air. This will free up the space and allow the dent to be fixed properly. Finally, use a heat gun or an oven to heat up the area until it is melted down and fixed.
