Do I need to sand and prep these before painting?

Yes. Sand the surface lightly with appropriate grit to promote paint adhesion, then clean thoroughly before applying your chosen finish. This ensures your final coat bonds properly and lasts.

Will these scoops interfere with door operation?

No. The scoops are designed to sit along the rocker and quarter panel without encroaching on the door swing area. Verify clearance visually before final fastening to confirm fit with your specific vehicle's panel gaps.

What fastening method is required for installation?

These scoops mount to factory panel locations using existing OEM mounting points. Verify bolt hole alignment with your vehicle's frame before committing fasteners, and refer to your service manual for proper torque specifications.
