Problem & Quick Assessment
- Identify bumper material (plastic, painted metal, unpainted metal)
- Gauge scuff depth (surface abrasion, paint loss, substrate exposure)
- Decide quick fix vs full repair
Decision Guide: Material & Scuff Depth
- Plastic bumpers → fine‑cut compound, soft pad
- Painted metal bumpers → medium‑cut compound, clear‑coat sealant
- Unpainted metal bumpers → sanding disc (1500, 2000 grit) + primer
