scratches on rear and front bumber

[00 LSM GTS]

someone keyed the my car but luckily it was only on the bumber .. anyone know how to make it look less ovious? it's not deep, but long and noticable.
I also scraped the front right side of my front bumper when i was parking, that was is pretty deep but on the underside of the bumber so it's not really noticable, any tips on how to remove or paint over that?

for the keyed bumper-try 3M mark swirl remover. there are 2 kinds, one for light cars and one for dark cars. After doing that, make sure u apply some wax over it. the 3M swirl remover does wonders.
