Do I need seam tape or gap filler between the panels and my factory body?

Gap filler or seam tape is recommended where new panels meet the OEM body to create a clean transition and prevent water infiltration. Your choice of gap filler or tape depends on your preferred finish method and climate conditions.

Can I paint each panel separately before installation, or should I install first and paint as a complete kit?

You can paint panels before or after installation—both approaches work. Painting individually allows easier handling and masking; painting after installation creates seamless body lines. Either method works; choose based on your workspace and preferred workflow.

What's the best way to prep FRP panels before painting?

Sand the surface with appropriate grit to scuff the finish, then wipe clean to remove dust. Follow your paint manufacturer's prep instructions for primer and topcoat compatibility to ensure proper adhesion and a professional finish.
