Do I need to sand and prep each piece separately before painting?

Yes. Each panel Requires Surface Prep, meaning the surface is prepared for adhesion. Sand lightly with appropriate grit before your primer and topcoat application, then paint all pieces together or individually depending on your spray setup. Consistent prep across all four pieces ensures uniform finish quality.

Will I need gap filler or seam tape where the side skirts meet the body?

Depending on your fitment and panel gaps, you may need flexible sealant or trim tape at the skirt-to-door junctions. Test-fit all pieces first, then evaluate gaps. Many builders use flexible polyurethane seam sealer or self-adhesive trim to bridge any inconsistencies and protect underlying paint.

Is this kit for convertible and coupe models, or convertible only?

Convertible trim only. This kit is engineered for the convertible body line and will not align properly on hardtop or coupe variants. Verify your vehicle's trim before ordering.
