Can I paint each piece separately before installation?

Yes. Painting the panels off-vehicle is the standard approach and gives you better control over finish coverage and color matching. Mask mounting areas before painting to ensure clean fitment during installation.

Do I need gap filler or seam tape between panels?

Gap management depends on your fitment tolerance. Have your vehicle available during final prep to test fit all three pieces and assess any gaps. Standard automotive seam sealer or gap filler can be applied after paint if needed for weatherproofing.

What should I use to prepare the FRP before painting?

Sand and prep the surface with your chosen finishing system before applying color coat. Follow your paint manufacturer's recommendations for surface preparation on FRP substrates to ensure proper adhesion and finish quality.
