Do I need to paint each piece separately before installation?

You can paint the pieces on the bench before bolting them on, or paint them after installation — either approach works. Painting off the vehicle gives you better coverage and easier handling, but requires masking during install. Most builders prefer to prep and spray each piece individually, then install, for the cleanest finish.

Will the side skirts affect jack point access?

Check your jack point locations before final installation. Some OEM jack points sit near the rocker line where side skirts mount. If clearance is tight, you may need to modify your jacking method or use a low-profile floor jack. Verify fitment to your specific vehicle's undercarriage before committing fasteners.

What prep is needed before painting these FRP pieces?

Sand the surface with appropriate grit to remove the glossy gelcoat and create tooth for primer adhesion. Wipe down with a tack cloth to remove dust, then apply your chosen primer system. FRP surfaces are stable and bond well to modern primers — no special sealer is required beyond standard prep.
