Will these affect my jack point access?

Raven-style skirts sit flush along the rocker. Factory jack points remain accessible; verify clearance with your jack before first use if you have an aftermarket suspension setup.

How vulnerable is FRP to road debris?

FRP is tougher than stock plastic but not impact-proof. Rock strikes and curb contact can dent or chip it. Raw FRP finish gives you the option to touch up minor scuffs before or after paint.

Can I paint these without sanding?

raw FRP condition means the surface is prepped for paint adhesion. Light scuffing before your basecoat is always recommended for best results, but no heavy sanding is required.
