Is your car bumper scuffed or scratched? While not as severe as a crack or dent a trip to a repair shop not only costs quite a bit, but they will probably need to keep your car for a day or two.

So why not fix it yourself?

In this instructable, I am now going to show you how to repair a scratched plastic or fiberglass bumper cover on your own, in a fraction of the time, and at a fraction of the cost.

What you need:

Step 1: Apply Abro Tape

Apply Masking Tape

Mask off areas around with the abro tape at the damaged area which you do not want to be sprayed with spray paint.

Step 2: Sand Bumper

Step 2: Sand Bumper

use sandpaper of 300 grits and above to get the smooth finishing, Using moderate pressure, sand the damaged area of the bumper until you have smoothed the scratches out.

Step 3: Clean the Panel with a smooth cloth

Step 3: Clean Panel

trust me this phase is so important, there should not be any dust particles or hard surface left over the scratches, Wipe down the panel with a smooth cleaning towel, then clean the entire area with wax and grease remover.

Step 4: Fill Scratches

Step 4: Fill Scratches

Use fine quality polyester putty which is suitable for car dents, dont go for normal asial paints putties which were actually used for walls and other stuff, automotive putties are differnet. i suggest you to go for Roberlo 61039 Plus-12 Polyester Putty (2.5 Kg) which is of fine quality.

If you find any scratches that will not sand out, fill them with a thin layer of scratch-filling putty. Give the putty 5 to 15 minutes for it to harden, then sand it using some coarse sandpaper.
You might need to repeat this step again in order to smooth everything out.

Step 5: Polish the Repair Area

Step 5: Scuff Repair Area

Polish the Repair Area with the fine quality sandpaper until you see a clean and smooth surface. put a light with a torch and check if the surface is balanced.

Step 6: Apply Prime over the Bumper

Apply multiple coats of paint from a distance of about 10-12 inches.

If you encounter any bumps, cloudiness, or what looks like “cat” scratches wait five minutes, sand it again, and re-apply the paint.

If your car is silver or gold or any metallic colour and you notice stripes, following up with some vertical passes.

Step 8: Clearcoat Layer

Step 8: Clearcoat Layer

Clear coat is something which will give metallic look to the base coat we have applied.

Give the paint 5 to 10 minutes to dry, then apply a light layer of clearcoat.

Wait for 2 to 5 minutes and slowly apply a heavier layer, overlapping each pass by around 50%.

Give the clearcoat 10 minutes to dry before removing the tape and paper.
