What prep work is needed before painting?

Sand the primer surface with standard automotive sandpaper and wipe clean before applying your base coat. FRP doesn't require special treatment — use the same prep process as you would for any primed panel. If you're applying a clear coat finish, ensure the surface is dust-free between coats.

Do these panels require any fastening hardware?

The panels ship without fasteners. Hardware requirements depend on your mounting approach — some builders use existing factory holes, while others drill custom points for their preferred attachment method. Verify your intended mounting surface before purchase so you can source appropriate fasteners for your setup.

Will these panels fit over my current fenders, or do they replace them?

These are over fenders, meaning they mount on top of or alongside your existing panels to widen the wheel arch. They do not replace your original fenders. Check your vehicle's current body panel condition and mounting points to determine your installation path.
