Do I need to paint each piece separately, or can they be assembled first?

You can paint the panels either before or after fitment — it depends on your workshop setup and preference. Painting them separately before installation often gives cleaner results and easier handling, but some builders prefer assembly-first for seamless color matching across gaps. Either approach works with FRP.

Will gap filler or seam tape be needed between the panels and OEM body lines?

FRP panels are precision-molded to match OEM mounting points, so gaps should be minimal. Standard body shop prep — sanding, alignment, and primer — handles any minor transitions. Whether you use gap filler is a refinement choice, not a requirement.

How many pieces are in this kit, and what does each one cover?

This is a four-piece set that covers the full body modification — front fascia, both side sections, and rear panel. Verify your intended coverage against the W-1 styling diagram before purchase to confirm it matches your build plan.
