Will I need fasteners or adhesive to mount these?

These use factory mounting points — check your vehicle's rocker area where the original louver mounts or where clips sit. Bring fasteners matching your OEM hardware pattern; clips or bolts typically come from your local supplier once you confirm attachment type with a test-fit.

Can I install this myself, or do I need a shop?

Installation is straightforward if you're comfortable removing interior trim panels and working around the rear glass. You'll need basic hand tools and patience. A second set of hands makes panel removal easier but isn't mandatory.

Do these need primer or paint before installation?

Louvres arrive unfinished — they're designed to accept primer and paint. Sand the surface, apply primer, then topcoat to match your exterior. Paint before final installation to avoid overspray on glass.
