Will this spoiler interfere with the trunk seal or hatch operation?

Roof spoilers are mounted to the roof panel, not the trunk or hatch. Verify clearance with your specific sunroof or roof rack setup before installation to avoid contact points during closure cycles.

What surface prep is needed before I paint this?

Sand and prep the surface with standard automotive prep before applying your chosen topcoat. The FRP is ready to accept paint once cleaned and scuffed per your paint system's requirements.

How stable is this spoiler at highway speeds?

FRP roof spoilers are engineered for aesthetic presence and mild aerodynamic effect at street speeds. Ensure all mounting fasteners are properly torqued per the installation guidance and verify that no fasteners are left loose before highway driving.
