Will these skirts interfere with jack point access?

No — these panels are designed to sit below the factory rocker structure. Verify your jack point locations before installation, and you'll have clear access during maintenance.

Do I need to paint before or after installation?

You can do either. Sand and prep the surfaces before mounting for easier tape masking, or install first and wrap edges with painter's tape. Both methods work; choose based on your workspace setup.

What ground clearance change should I expect?

These rocker panels sit along the existing rocker line with minimal vertical extension. Ground clearance remains essentially unchanged compared to OEM rockers.
