Will this lip scrape on speed bumps or driveway lips?

FRP lips sit lower than the bumper fascia and can contact steep approaches or high speed bumps. Check your typical driveway angle and parking lot transitions before installation. If ground clearance is tight, you may want to test-fit first or plan your entry angles accordingly.

Does this material flex or stay rigid once installed?

FRP is a hard panel material. Once mounted to the bumper, it remains rigid and does not flex under normal conditions. It absorbs minor impacts better than brittle plastic, but is not designed as a crumple zone—treat it like your factory bumper fascia.

What prep work do I need to do before painting?

Sand the entire lip with appropriate grit to dull the primer surface, wipe clean, and apply your chosen base coat and clear according to your paint system's instructions. Since it ships raw FRP, no stripping or undercoat removal is needed—start sanding and go straight to color.
