Do these panels protect the original jack points?

Yes. These rockers are designed to mount over factory hardware without blocking access to side jacking points. Verify clearance on your specific vehicle before final installation, and always use proper jack stands on the frame for any suspension work.

What prep is needed before paint?

Sand the surface to establish tooth for your chosen base and clear coat. Clean off dust and follow your paint supplier's guidelines for primer, base, and topcoat application. FRP accepts standard automotive finishes without special sealing steps.

Will these fit if I've modified my suspension or added a body kit?

These rockers mount to factory rocker locations. If you've added wide fenders, lowering springs, or other aero components, measure the clearance between the new side skirts and any adjacent parts before committing to installation. The two-piece design lets you fit one side at a time to test fitment.
