Will this lip scrape on everyday driving?

Ground clearance depends on your suspension setup and how far the lip extends. Measure your current lip-to-pavement distance before installation and compare it to the RBS profile. You may want to account for speed bumps and driveway angles in your assessment.

Does this FRP material flex, or is it rigid?

FRP is a rigid hard panel construction. It won't flex under normal driving, but it can absorb minor impacts better than brittle plastic. Avoid heavy contact with curbs or low obstacles—FRP can crack under direct stress.

What prep work is required before painting?

Sand and prep the surface with appropriate grit progression before applying your chosen finish. The panel ships in unpainted condition to give you full control over color matching and coating type.
