Unfortunately, it happened already.

I backed into another vehicle. Minor damage, but I did chip the paint on the bumper. I have estimates so far of $500 and $300so I figure it will be at least $500 to fix it right.
I would like to know others' opinions and experience with any repair body work and what I need to be looking out for. I have been told the bumper will have to come off (lights and badging removed) so I guess I'm concerned everything gets put back like it was.
Thanks for your advice and input as always.
