Will this affect my front ground clearance?

The lip extends the lower fascia line but does not significantly alter approach angle. Check the lowest point of your vehicle's current bumper, then measure the lip's projection to compare against local driveway and speed bump clearance at your typical entry angles.

Can FRP flex, or is this a rigid panel?

FRP is a rigid hard panel with minimal flex. It's designed to hold shape under normal driving and minor contact, but it is not impact-absorbent like urethane. Avoid heavy scraping or direct curb contact to preserve finish integrity.

What prep work does the FRP surface need before painting?

Sand and prep the surface with appropriate grit before applying your chosen base coat and clear. The factory gelcoat provides a stable foundation — no grinding or stripping required if the surface remains undamaged during storage and install.
