Depending on how bad the bend/kink is, it can be fixed. All you would really have to is bend the corner and smooth it out with bondo. Sand it all the way down to metal, then start the body work. Paint blending is realtively easy just make sure you mask off everything else very well. Here is a quick manual on body work if interested. Pull out the bend as close as you can to original, then put on some bondo. You can basically shape the bondo anyway you want to. Once you believe that you have it as close to the original as you can, spray some Guide Goat (or you can use black spray paint) really lightly and sand it again with 300 grit. This will show any low spots, pin holes, imperfections, etc. Put a little bit more bondo and continue the process until the next time your spray the Guide Coat, all of it sands off easily. After your done lay down about 3-4 coats of sandable primer and sand that down using 500 grit sandpaper. That'll help take away anymore imperfections. After that spray down 4-5 coats of base, then 5-6 of clear. Make sure you masked off quite a bit of space so you can blend it all together afterwards. After your clear dries, wet sand the area and surrounding area using 1500 grit and then 2000 grit and then use rubbing compound. After the rubbing compound, you can polish and wax. And you are done. Same thing with the bumper. You can fix any gouges from the impact with bondo as well. And just sand it down smooth. Make sure you scuff up the whole thing prior to spraying anything on it. But it's also pretty straight forward as well. If you have any other questions, let me know. Hope this helps......
