Will these panels obstruct access to the factory jack points?

Check your vehicle's jack point locations before final installation. FRP panels can be trimmed at mounting areas if needed to preserve jack access. Verify your setup during a test fit.

Do I need to sand and prime these before painting?

Yes. Sand the surface to prepare it for adhesion, then apply your chosen primer and paint system. The raw FRP condition means the panels have no factory paint — finishing is up to you.

Will FRP hold up better than the original steel rockers?

FRP won't rust or dent as easily as steel, and it's significantly lighter. It does require paint and proper prep to maintain its finish. Regular washing and waxing will keep it in good shape long-term.
