depends on how deep the scratches are. Take it to a good detailer to take a look. People always try and fix things themselves and it would only be a little more to have a pro do it. There is no way to give you an estimate without seeing it.

Just got some heavy scratching on my rear bumper from loading items into the trunk of my black 2003 limited sequoia. I bought some furniture in large boxes that were loaded into my trunk by a store employee. When I got home I noticed some large scratches that I tried polishing out with a wax polish or even 3m scratch remover. Scratches are still there. What can I do? Do I need to take it to a body shop? Does Toyota sell a painted rear black bumper? How much will this cost to fix? Need some reccomendations.

 

Scratches that you can feel with your fingers are a lot harder to hide with wax and polish but there are professional detailers who can work wonders. There's a guy around here in a mobile shop van who drives around to different dealerships and does a great job fixing up things like that.

For the smaller scratches (that you can't really feel) I've found that Eagle One NanoWax works pretty well.
