Do these extensions mount to the original rear bumper, or do I need to drill new holes?

These extensions are engineered to use factory mounting points on the rear bumper structure. Before installation, verify your vehicle's original mounting holes are accessible and match the spat alignment. No drilling is required if factory points are present.

What surface prep is needed before painting?

Sand the entire surface and clean thoroughly to remove dust and oils. A clean, properly prepped surface ensures paint adhesion. Choose a quality automotive paint system suitable for polyurethane substrates and apply according to the paint manufacturer's instructions.

If my extensions arrive with slight deformation from shipping, how do I restore the shape?

Polyurethane can temporarily deform during transit due to pressure and temperature changes. Place the extensions in direct sunlight for 30 minutes to an hour — the material will gradually return to its molded profile as it warms. This is normal and does not indicate a defect.
