Will this fit my vehicle if it has factory fog lights or parking sensors?

Factory fog light cutouts are specific to OEM bumpers. Before installation, verify whether your current bumper has fog holes or sensor cutouts. If your bumper has these features, check the coverage or alignment on this cover against your existing setup to determine if any cutting is required.

Does this bumper fit the C63 model?

No — this cover is designed for the standard C Class only. The C63 has different mounting points and structural requirements. Verify your vehicle model before ordering.

What prep work should I do before painting?

Sand and prep the surface to promote paint adhesion. Apply your chosen primer and finish coats according to the product manufacturer's instructions. The FRP surface responds well to standard automotive paint systems when properly prepared.
