Will this interfere with the trunk seal or weather stripping?

The Sigma profile sits low on the bumper line and does not extend into the trunk opening. Verify clearance by dry-fitting before final installation, especially if your vehicle has non-OEM bumper modifications or aftermarket weatherstripping.

Does the rear bumper need to be removed for installation?

Most installs use factory mounting points and do not require full bumper removal. However, access and fitment may vary depending on your current setup. Review the mounting area and the panel's contact points before committing to fasteners.

What prep work is needed before paint?

Sand the surface with appropriate grit to scuff the gelcoat, wipe clean, and fill any small voids or imperfections if needed. Follow your paint supplier's guidelines for primer and topcoat adhesion on FRP. Do not skip surface prep—paint adhesion depends on it.
