Can I paint each piece separately or should I assemble first?

Paint each panel individually before installation. This gives you better access to edges, seams, and undercuts. It also lets you cure and inspect each piece for finish quality without worrying about masking off assembled gaps.

Do I need gap filler or seam tape between the kit pieces and factory panels?

Check the fitment between each kit panel and your factory body before painting. If gaps exceed 1/8 inch, you can use flexible caulk or gap sealant rated for automotive use after paint. Most installations work without additional filler tape when panels are properly aligned and fastened.

How do I know which fasteners to use for installation?

Refer to your vehicle's service manual for OEM fastener specifications at each mounting point. FRP panels work with standard automotive fasteners—your manual will specify the correct size and torque values for your model year.
