  2. What is a bumper?

    • Answer: A bumper is a protective bar or structure at the front and rear of a vehicle designed to absorb impact in a collision, minimizing damage to the vehicle's body.

  5. How do you use a hand-held burnisher?

    • Answer: A hand-held burnisher is used by applying gentle, even pressure and smooth, overlapping strokes in one direction. Excessive pressure can damage the surface.

  9. What tools are needed to repair a bumper?

    • Answer: Depending on the repair, you might need a putty knife, filler, sandpaper, primer, paint, spray gun, masking tape, and potentially a heat gun for plastic bumpers.

  10. What is the purpose of burnishing?

    • Answer: Burnishing improves the surface finish, increasing smoothness, hardness, and luster. It also increases corrosion resistance in some cases.

  11. What is the purpose of a bumper?

    • Answer: The main purpose is to protect the vehicle's body from minor impacts and collisions, reducing repair costs and potentially preventing more severe damage.

  12. Describe the process of burnishing silver.

    • Answer: Silver is burnished using a smooth, hard tool, applying even pressure in overlapping strokes. The process may involve several stages to achieve a high polish.

  13. Describe the process of replacing a damaged bumper.

    • Answer: This involves removing the old bumper (often requiring removing fasteners and possibly other components), installing the new bumper, and securing it properly.

  14. What are some common problems encountered when burnishing?

    • Answer: Uneven surface finish, scratches, and too much pressure causing damage are common problems.

  15. What are some common problems encountered when repairing a bumper?

    • Answer: Imperfect paint matching, improper filler application leading to cracks, and insufficient curing time for paint are common problems.

  16. How do you choose the right burnisher for a specific job?

    • Answer: Consider the material being burnished, the desired finish, and the size and shape of the surface.

  17. How do you choose the right replacement bumper for a vehicle?

    • Answer: Ensure the bumper is the correct make, model, and year for your vehicle. Consider material and color options.

  18. What is the difference between polishing and burnishing?

    • Answer: While both improve surface finish, polishing uses abrasives to remove material, whereas burnishing smooths the surface without significant material removal.

  19. What is the difference between a bumper cover and a bumper?
