Will these skirts block access to my jack points?

No. Verify your vehicle's OEM jack point locations before final installation — these skirts are designed to sit below the rocker line without covering access holes. Test fit and mark clearance areas during mock-up.

Do I need to drill new mounting holes, or do they use factory attachment points?

Test fit the skirts against your existing body line first. Factory rocker reinforcement points and clips are your best anchor; if additional fasteners are needed, mark and measure twice before drilling. This varies by individual install condition.

What prep work is required before painting?

Sand the surface and wipe clean before applying your chosen basecoat and clear. Standard automotive surface prep applies — refer to your paint manufacturer's technical sheet for grit recommendations and primer compatibility.
