Do I need to prepare the surface before installation?

Yes. Sand the mounting surface and the fender's contact areas to ensure flush fitment. Clean away all dust and debris before bolting down. This step takes 15 minutes per side and makes the difference between a tight gap and a sloppy one.

What do I need to do before painting?

Sand the fender with appropriate grit and apply a quality primer to all exposed FRP. This seals the material and gives your topcoat a solid foundation. Follow your paint supplier's recommended prep steps for FRP surfaces.

Will these work with my OEM hood and doors?

Yes. These over fenders mount independently of hood and door panels using factory body anchor points. Verify clearance with your doors and hood in both open and closed positions before final torque, as fitment can vary slightly based on prior accident history or panel alignment on your vehicle.
