Rubber lip....body lemonade easy to put on. DONT buy lip specific stuff on ebay as its expensive and rebranded as all it is, is a garage door seal.

Its called Gap stop garage door seal. You get nails and double sided sticky tape. You put the sticky tape on one side and and pull the tape off as you work your way round the bumper. The tape its very strong. So stong its ripped the new paint off my lip.
Plus its very flexible so you cant snap or break it when hitting kerbs or bumps.
