Okay...so if you have a serious dent that you can't pop out, Bondo is definitely a good option. After your done shaping it, you can prime it, paint it and then clear it. If you just have a thin scratch though, Bondo is really not necessary. You can just fill the scratch with touch-up paint until you completely fill the scratch and then sand it down to level it and then compound it and polish it. Hope that helps.

Krud Kutter 8 oz. Rust Remover and Inhibitor at Home Depot. Use 000 steel wool and rub the rust off. I used it in a set of chrome olympic weights worked like a charm.

If the bondo is too thick it's just going to crack. I believe you have to use a special filler made for these bumpers. Additionally you need to sand primer and feather the edges before you blend the paint. Don't mask with hard lines and open up the area beyond just the damage.

What I don't understand is. I put the bondo in the crack. And I laid down a fresh coat of paint. If I sand the paint smooth won't it come off. Or am I going to have a bump either way

The material under the paint needs to be sanded smooth. Make it as perfect as possible because paint isn't going to hide anything in fact just the reverse it will show the imperfections.
From what I can see in the picture the bondo isn't smooth and you have hard edged on the factory paint around the repair. If the damage area is 4 inches you need to prep a bigger area say 8-1 inches. This will allow you to feather (lightly) sand or blend the good area into the repaired area. After it is all preped up you should be painting at least half the bumper. This is an old painters technique that tricks your eyes where the paint blend isn't noticable.
Does this make sense to you? Search YouTube there are plenty of bumper repair DIY videos. Also reverse masking will not leave a hard edge. There are videos on that as well.
IMO the only way to get rid of those hard paint edges around the repair is to sand them smooth so yes you will be taking off some of the paint just applied. Prep again and respray. Remember blendiing is your friend.

Thank you do much for the speedy reply. I sanded with 80 grit then followed up with 220 and then 400
I laid some plastic adhesive and then I just put down some primer. I choose a greenish brown primer so it can really bring out the color and hide any imperfections in case I ###### upView attachment 14173
I went up to a place called total auto center and they were so helpful. I talked with this guy named chuck and he really helped me out to choose the right paint. I'm about ready to sand the primer and lay my first cost of paint. Wish me luck.
