To remove bumper scuffs, remove the bumper, identify the type of plastic it is made from, then buy the appropriate chemical fillers and tools. You need a large space to work in with adequate ventilation.Continue Reading
Each make and model of car has specific tabs and screws that hold the bumper in place. Carefully undo any fastener attaching the bumper, then slide it out of the tabs before removing the bumper from the car.
Look on the back of the bumper for a stamp or label containing information about the bumper and its material.
Once you know the type of plastic you're working with, go to a local auto shop to purchase the appropriate filler, cleaning supplies, prepping solvent, and sandpaper.
Slightly scuff the damaged area, then thoroughly clean the bumper with a surface cleaner. Rinse the bumper, and let it dry. Once dry, wipe the damaged area with prep solvent.
Mix the hardener and repair adhesive on a piece of cardboard or paper. Smooth the damaged area with 24 or 80 grit sandpaper, depending on the type of plastic the bumper is. Form a "V" groove on the front and back of the damage.
Carefully fill in the repair site with the filler. If the damage is extensive, use masking tape or fiberglass repair tape to hold the bumper in place as you apply filler. Once the material has hardened, sand it with 80 grit sandpaper. Refill any spots that are now low. After it has rehardened, sand with 80 grit then 120 grit sandpaper. Fill the damaged area with repair material to restore the contour of the bumper, and finish by sanding again with 400 grit sandpaper.
