Will this add or reduce my ground clearance?

This lip extends downward from your lower bumper. Verify your driveway slope and parking lot approach angle before installation. If you frequently bottom out, test-fit and measure the clearance gap at your steepest angle.

How flexible is FRP, and will it flex under minor contact?

FRP is a rigid panel construction, not flexible. It's built to hold its shape and absorb minor road impacts without deforming. For heavy scrapes or parking lot contact, the panel may crack rather than flex — inspect regularly and sand any stress areas before they spread.

What prep work do I need to do before painting?

Sand the surface with fine-grit sandpaper and clean thoroughly to remove dust and oils. Apply a quality primer designed for plastic substrates, then your base coat and clear. Proper surface prep is the key to paint adhesion on FRP — skip this step and finish will peel within months.
