2009 Challenger SRT8 - Two Stage Paint Correction & Engine Detail

[zmcgovern45]

This customer contacted me on Facebook regarding his Challenger SRT8. It is not his daily driven vehicle, and he wanted it cleaned up so it would look it's best when he got to take it out on nice days. The paint had rather deep swirls and scratches, as well as etched water spots and bug splatter. I was battling some ridiculously hot weather (2 days of 97 degrees, heat index of 103) and I gave it everything I could for a two step correction, but there were still some heavier defects that I was unable to correct within the time I had to work on this vehicle. Overall I'd say I achieved around an 85% correction, and it looked great when it was completed.

Before

The car was dropped off and I had some time to get some pictures before the driveway was in full shade and I could begin washing.

Even though the car was dirty, I could clearly see the swirls and scratches. Also the car had plenty of water spots on the paint which always makes me assume there will be some etching in the clear coat.

Here's a new one... a spider had made its home in the corner of the rear window.

The faces of the wheels were not too dirty, but the barrels of the wheels needed a good cleaning.

Exhaust tips were in pretty good shape, but again, there were more water spots.

Engine wasn't too dirty, but there were tons of water spots on all of the plastic trim, as well as a layer of dirt and dust.

During

I began by cleaning the engine compartment. Notice the exposed air filter was covered before I started so it would not get wet. While I know it is unlikely for a little water to cause any problems... always better safe than sorry.

After a good rinsing, the engine was sprayed liberally with Meguiar's D103 APC+ (mixed 10:1) and scrubbed down with a soft brush. The engine was then rinsed and dried with a blower.

Next the wheels were cleaned using Sonax Full Effect wheel cleaner. This product starts as a neon green color and turns to purple as it reacts with brake dust, dirt, and grime.

You can see that there is not much of a reaction on the face of the wheels since they were pretty clean, however there is a river of dirt flowing from the barrels of the wheels.

The wheel cleaner was then agitated with a soft wheel brush and the barrels were cleaned with wheel woolies. Notice how clean the wheels are (both the faces and the barrels). The tires were then scrubbed down with Tuff shine tire cleaner and tire brush until the suds remained white (as shown), indicating the dirt had been removed.

With the wheels clean, I proceeded to foam the car, rinse, and then wash the vehicle using a proper 2 bucket washing method. The car was then dried with quality waffle weave microfiber and a blower to help get water out of all of the hard to reach places.

After the paint was washed and decontaminated (using fine grade clay) I was able to thoroughly inspect the paint. The metallic paint made it somewhat difficult to capture all of the finer defects in the camera, so you'll have to believe me when I tell you that it was worse than what you see here.

I was now ready to begin my test spot on the hood.

Due to the fact that there were a lot of deeper defects, it was determined that a heavy cutting compound (mix of D300 and M105) with a MF cutting pad would be required to remove that majority of the imperfections.

Door After Compounding

I took this 50/50 shot to show the difference final finish polishing makes. This is the section of the door shown in the previous photo... I put a piece of tape through that section and used a finishing polish (m205) on the upper portion. You can clearly see that the upper area is a much deeper, darker color... while the lower area has a considerable amount of marring/haze remaining from the heavy cutting compound.

This is that same section out in the sunlight. The rest of the area has been compounded, but only the small section in the middle has been polished. What a dramatic difference!

You can see how the haze looks in the sunlight. It creates a greyish, hazy finish on the paint. This is why it is crucial to follow up with a finishing polish on black paint after using an aggressive cutting compound/pad combo.

Again, another side by side shot showing the difference that finish polishing makes. The left side has been polished and the right side has only been compounded. You can see the improved clarity in the left side compared to the right.

50/50 shot of the door... you can see the farthest portion of the door is a dramatically improved. Swirls, Scratches, and some pretty bad holograms are all present on the uncorrected area.

and after compounding

Inspecting the results in the sunlight after all of the correction work was completed.

All that compounding and polishing created quite a mess. Dust was everywhere. The paint was then washed again to remove the dust and any existing polishing oils.

After

The car was coated with Black Light Sealant and then Pete's 53 Wax, a great combo for dark paint. The paint looked fantastic after all of that hard work!

Look at that metallic flake! No Swirls here! (I like to see how many sun stars I can put on the paint at one time - only count 2 in this picture)

^Winner... I count 7 sun stars in that pic. No visible swirls.

Great reflections

Engine and trim was properly dressed. Everyone knows a clean engine is more powerful than a dirty one.

Exhaust tips were polished up... showing off the mirror like paint, too.

Looking good! Awesome, deep, dark black paint. Gorgeous.

Waiting to be picked up... Guess I should do a photo shoot with some time to spare!

Had to lay in the itchy grass to get this angle... totally worth it.

This one could belong in a magazine if I do say so myself (my favorite)

As always, thanks for looking! Questions and/or comments are greatly appreciated!

I get excited every time I see you have a new thread going Zach. Excellent work again. Do you ever send the owners copies from the photo shoots?

Awesome work! Did you find the clearcoat to be of the hard, scratch resistant type?

Thanks Todd!! Much appreciated!

Nice work !

Thanks! I always send them a follow up email with a link to the complete write up on my site. Occasionally customers will ask me to do an off-site photo shoot after the detail, and for those particular situations they often ask for high res images... usually no one bothers to ask for the images I take for my own personal enjoyment.

Thanks! It was quite hard, but was still easily marred by cutting pad/compound. Interesting paint to work with.

Awesome job! I like seeing the 50/50 shot between compounding and polishing
