What prep work does the louver need before paint?

Sand the surface lightly to promote paint adhesion, then apply your preferred basecoat and clear. If you're using an epoxy primer first, ensure compatibility with your topcoat system. Check product data sheets from your paint supplier to confirm specifications.

Do I need any adhesive or fasteners to install this?

Installation method varies by mounting approach — some builders use panel adhesive, others use mechanical fasteners. Reference your vehicle's service manual and the louver's mounting surface to determine which method suits your build. Verify OEM glass attachment points before drilling.

Will the FRP stay durable in direct sunlight?

FRP holds up well under UV exposure when properly sealed with clear coat. Once painted and protected with a quality finish, the louver will maintain color and resist degradation. Avoid prolonged exposure to intense solvents or harsh chemicals after curing.
