Do I need to paint each piece separately, or can I paint them assembled?

Paint each piece individually before installation. This ensures even color match, proper coverage inside seams, and avoids overspray on areas you can't reach once everything is bolted down. Mask off any mounting tabs or bolt holes before spraying.

Will this kit need gap filler or seam tape between panels?

The four-piece design engineered for factory-style panel alignment, so gaps should be minimal. If you find slight gaps after dry-fitting, flexible urethane filler or color-matched gap sealant works well — apply it after all pieces are mounted and tightened.

What surface prep is required before painting?

Sand the surface with appropriate sandpaper grit for your primer type, then wipe clean of dust. Follow your primer and paint manufacturer's prep guidelines — the FRP surface is already sanded, so you're just scuffing for adhesion and cleaning before application.
