Hi Deep,
When you say repair? I cant really see from the photo, but that looks like a plastic bumper... (am i correct?) If this is so, and it has been scuffed/deeply scratched to where paint has been taken off, the best adive is to get the bumper blown in. This can cost from £50-90 depending on who you use. You shouldnt have caused any real damage, as it looks superficial. You just need the paint sorting and the bumper possibly heated and moulded back to original shape. Any professional body shop can do this for you.
Hope this helps.
