Do these require any prep or finishing before installation?

Sand and prep the surface before applying your chosen finish. Bare FRP can be painted with automotive urethane or clear-coated for UV protection. Allow curing time per your paint manufacturer's specs before handling or installation.

What fasteners do I need to mount these?

The skirts mount to existing rocker panel attachment points. Verify your vehicle's OEM mounting holes and obtain fasteners rated for exterior body panels. Refer to your vehicle's service manual or suspension points guide for proper hardware specs and torque values.

Can FRP crack or chip if hit with road debris?

FRP is durable but can be dented or scuffed like any plastic panel. Impact protection depends on installation height and your driving environment. A quality clear coat finish adds an extra layer of protection against UV and minor abrasion. For maximum longevity, keep the panels clean and inspect regularly for any prep work needed.
