Anything anyone can recomend? Looking for like an over the counter solution at your local auto parts store. I think someone keyed my car, nasty scratch on the back. It's kinda deep, it's a bright white streak on my blue car. Thanks!

I don't think there is any miracle solution that would work on a deep scratch. I'd try a good wax after a wash. Then I'd look at it and see if it looks horrible enough to pay someone to fix it.

I used to love watching those infomercials. They don't have any more of that cool car stuff though. I loved watching the ones about those miracle car waxes, Motor Up, DuraLube, etc., etc... Now all I see is that damn Showtime Oven. My mom already got one of those, it's time for something new!

that bright white streak you're seeing is probably the primer layer of the paint and/or could possibly be the sheetmetal.
there's really no solution to this problem. you can try to tack on touch up paint, but it'll look like shit, even if you do a light color sand, buff and wax. Make sure that the bright white is primer and NOT sheetmetal (due to rust reasons. if it is sheetmetal, you need to cover that section with something to resist rust.
I personally say just to leave it alone. It might look bad now, but a single streak is a lot better than a built up (with touch up paint) streak with differing colors. Be careful if you try to touch up.
There are those scratch solution infomercial miracle wonder things, but i'm not sure how well they work. you may just want to fill in the white streak by using that colored miracle solution and then use rubbing compound to rub out the affected area, and then buff it out, wax, buff.

It doesn't look like it's all the way to the metal, probably just the primer. I think I'll have to cough up the money and let a professional handle it. I am a little worried about the rust, just in case. Thanks for the advice (from everyone!). I was thinking about trying out one of those infomercial products like Karizma mentioned, but they've always looked a little too shady.

I actually broke down and bought something that was being sold as an infomercial. That stupid Ab-energizer. It's supposed be like doing 500 situps in a few minutes, all by electro, muscle stimulation (EMS).
I was so excited. I put on the minty smelling conductivity gel (nevermind the images of Jack Nicholson having this crap spread on his temples in One Flew Over the Cukoos Nest. They used it for shock therapy). Then you set the level and hit the power button....YOWZAAAA, I damn near electrocuted myself!!!!! You won't believe how hard it is to find the freakishly small off button when you're flailing uncontrollably!
I decided to get rid of the hellish device and gave it to my ex-girlfriend on her birthday. hehehe.
You know what? I think I'll post this as a tnew topic.

Those infomercial things will never be able to bring back paint where it is scraped off.
Btw, fuckers that key other peoples' cars should get socked in the face.

Here is the correct way to do it and what bodyshops would charge you for
its a little bit of a chore to do by hand but its very doable to do it without a Porter cable or Makita.
You’d be hard pressed to find a car on the road that does not have paint chips and parking lot scratches. While good detailing practices can’t prevent nicks and scratches, repairing them will restore your car’s “like new” appearance. In this article, I discuss the methods I’ve used for years to repair chips and minor scratches.
What’s Possible, What Isn’t
Touching up small nicks and scratches is well within the skill of most do-it-yourself car enthusiasts. Some nicks can be quickly repaired with a small dab of touch-up paint, while others will require more time, effort and skill. It’s important to know what you should and shouldn’t tackle based on your knowledge of paint and tools.
By far the easiest colors to repair are black and white. Black and white are very forgiving on shade variations. Conversely, metallic paints (those with metal flakes) can be quite difficult to match perfectly.
Before you get started repairing nicks and scratches, you should know what to expect. Small nicks are easy to repair by filling the nick with paint, leveling the filled area, and buffing the repair area to blend and restore luster. Repairing small scratches, from a key or shopping cart, is similar, but more time consuming. Fixing a ding (a small dent which may or may not have a nick out of the paint) is not commonly possible by the do-it-yourselfer.
Here are some other things you should know:
If you know your car’s factory paint code, you can purchase an exact color match touch-up paint from your local dealer. If you don’t know the factory paint code, look in your owner’s manual for the location of the code, or ask your dealer. If you have a late model car, chances are you will find a color match at your local auto parts store.
Use a small artist’s paint brush (#2 is ideal) or a round, wooden toothpick to apply the touch-up paint, not the fat brush included with the bottle of touch-up paint.
Always test the touch-up paint for color match in an inconspicuous area.
The area to be repaired must be perfectly clean and free of wax, rust and oils.
Don’t attempt a touch-up if the temperature is below 60 degrees F.
Here’s what you need to properly repair nicks and scratches:
* Color matched touch-up paint
* Automotive or metal primer
* Citric acid based cleaner like P21S Total Auto Wash
* Prep solvent (Prepsol) or denatured alcohol
* Foam swabs (from electronics supply) or pop swabs containing alcohol
* Meguiar’s Unigrit Sanding Block and 3M 1200 grit wet & dry sand paper
* Medium grit hand rubbing compound
* #2 Artist’s paint brush and round toothpicks (wood)
* Cotton terrycloth towels
* New Pencils with unused erasers
* Rubber cement
* Plastic cups
* Blue masking tape (easy release type)
* Large diameter paper hole punch (hand type)
Preparation Process
Before applying paint, you must prepare the chip to accept paint. Although paint may adhere for a while to a chip with rust, dirt or oil, eventually the repair will fail. The preparation process begins the day before you repair the paint chips and scratches.
The afternoon before starting your chip repairs, wash your car. After washing with your normal car wash, spray the areas you plan to repair with P21S Total Auto Wash, allow to sit for a minute, then scrub well with your sponge. P21S Total Auto Wash will remove all wax and oil from your paint. Dry your car thoroughly and put it away for the night.
After washing your car, make up several sanding pencils. Use a hole punch to punch out a few dots from the 600 grit wet and dry paper. Apply the sandpaper dots to the end of your pencil eraser with rubber cement. Allow them to dry over night. You will use the sanding pencils to scuff-up and clean out nicks.
To make a chip ready for touch-up paint, you must make sure it does not have loose edges, clean it and sand it. I use a toothpick to check the edges of a chip. If loose or lifted, I use the toothpick to knock off the loose paint. To clean, I like to use denatured alcohol or Prepsol and a foam swab. I pour a little bit into a plastic cup and use a foam swab to clean the chip and surrounding area.
Next, I use a sanding pencil to cleanout the chip and rough-up the edges. Simply dip the sanding pencil into a cup of clean water, dab a few drops of water on the chip, and gently rotate the sanding pencil over the chip. Keep the area you sand as small as possible. Rotating the sanding pencil back and forth in your fingers 8-10 times should be enough to do the job. If the chip has exposed bare metal, or if you can see rust forming, use the edge of the pencil erasure to remove the rust. When finish sanding the chip, dry it with a terrycloth towel and clean it again with Prepsol and a foam swab.
The Touch-Up
Once the damaged areas are cleaned and prepared, you can begin the touch-up itself. If a chip exposed bare metal, you must primer the chip before the color touch-up. After mixing thoroughly, pour or spray a small amount of your primer into a plastic cup. Next, use a clean toothpick to apply the primer. I do this by dipping just the tip (2-3 mm) of the toothpick unto the primer. If I get a blob, I wipe it back.
Next, I touch the tip of the toothpick to the center of the chip and allow the paint to flow off of the toothpick into the chip. You will be amazed how well the capillary action works. If you prefer, you can use the #2 artist’s brush. Do not allow the primer to overflow the sides of the chip.
Allow the primer to dry for 2-3 hours. You can speed dry the primer with a hair dryer after allowing it to air dry for one hour. Simply wave the hair dryer 3-4 inches over the primered chip for 30-40 seconds. Do not touch the chips with your hands, as the oils from your skin will prevent the color coat from adhering.
Now, mix your color-matched paint thoroughly and pour a small amount into a clean plastic cup. As with the primer, use a clean toothpick or #2 artist’s brush to apply the color coat. Touch the toothpick or brush to the center of the chip and allow capillary action to pull the paint into the chip. Apply a small dab at a time and allow it to dry for 2-3 hours. You must repeat this process several times, so don’t try to fill the chip in one pass. Apply several thin layers, and you will get much better results.
The color touch-up process is complete when you have applied enough coats to slightly overfill the chip onto the roughed up area surrounding the chip. Once you’ve filled the chip, allow it to dry for another 24 to 48 hours. The longer the better.
I’m often asked if it’s necessary to apply a clear coat over chip repairs. I don’t think it’s necessary of adds any noticeable difference. If you get the proper touch-up paint from your dealer, it will match without using a clearcoat. However, if you’re a purist in persuit of perfection, substitute a clearcoat for the last 2-3 coats.
Level and Buff
Until you level or mill the paint repair down to the same plane as the original paint, all you’ll have is an ugly looking blob. This is easily done using the Meguiar’s Unigrit Sanding Block, which helps remove sags, runs and other isolated defects with surgical precision. Don’t forget to soak it over night before use as the directions indicate.
To level your paint chips, use you finger to put a small dab of car shampoo on the chip repair for lubrication. Next, use the Unigrit Sanding Block to mill the high spot off of the chip repair. I always pull the sanding block towards me. Never rub it back and forth or in a circle. When the block dries out, dip it into your bucket of water again. Keep the area well lubricated with water and shampoo. The sanding block will dull the paint. Don’t fear, as your polish will easily restore the luster. When the surface looks level, dry it with a clean towel and inspect with your finger tips. If you can feel a high spot, it needs more work.
The final step is to buff out the repair with a good hand polish. I like to use 3M Perfect-It Rubbing Compound or Eagle One Scratch Remover (a medium grit compound) followed by 3M Perfect-It Swirl Mark Remover or Meguiar’s Hand Polish. Apply the compound or polish to a clean terrycloth towel or applicator pad, rub into the paint area using a short back and forth motion (not in circles), then buff out with a clean terrycloth towel. Tada! The blemish is gone.

by the way that stuff GS scratch remover stuff is just EagleOne ScratchX renamed.
Its hardly effective and uses "fillers" and very very mild abrasives to try and cover up the
scratch. Its only effective for a week or two.
In order to properly remove major swirling/cobwebbing bring it to a pro-detailer.
or ask Ill probably put down a full "how-to" detail guide on how to clean/fix anything jacked with your car.
