A tale of two Stingrays Pt. 1: 2014 Z51 Coupe

The introduction of Chevrolet's seventh generation Corvette marked the return of the legendary "Stingray" moniker; something that caused significant buzz among enthusiasts and collectors eager to see if the new car would live up to the brand's storied past. Although opinions varied at the initial reveal, many faithful long-time owners lined up to be the first to get their hands on the latest technical and design marvel to emerge from Bowling Green Assembly.

Early C7s began shipping to dealerships on September 18, 2013. Among the cars in those first few shipments was a triple-black coupe equipped with the Z51 performance package and 3LT trim, destined for a hardcore enthusiast's Metro Detroit based collection. Like many of the vehicles in the initial batch, this one came with a number of paint-related issues which were unfortunately made even worse by the delivering dealership. My task was to identify and correct these issues as much as possible.

Before work could begin, I took the opportunity to inspect the car at the client's home and formulate a game plan. A few issues stood out immediately, and it became obvious that a substantial amount of compounding and polishing would be required to get this car looking its best again:

The entire car was covered in an abundance of swirls, scratches, and "buffer trails," left due to improper use of an aggressive pad and compound on a rotary polisher during the dealership's pre-delivery detail. As if that wasn't bad enough, my client also stated that he witnessed a technician at the dealership drop a towel on the ground, pick it up, and continue using it to wipe down his car. This sort of scenario is why many professional detailers educate our clients against letting dealers so much as wash their cars, let alone trusting them with the task of fully 'detailing' them; while certainly not all dealerships are so careless, the risk simply isn't worth it.

With a plan in place, the car was delivered to me for work to begin. Despite being well over a year old, it had only traveled just over 4,000 miles and was just moderately dirty:

A thorough wash and decontamination was performed to strip any bonded contaminants such as bugs, tar, tree sap, or ferrous particles from the finish, leaving the car clean ready for paint correction.

With the car now generally clean, first up for intensive work were the wheels, brakes, and suspension. In order to effectively clean and protect these intricate components, the vehicle was lifted and each wheel and tire assembly was carefully removed. Lifting duties were carried out using a heavy duty floor jack with a bolt-on cross beam under the front and rear frame cross-members. Jack stands were used to properly stabilize and secure the car to prevent dropping.

The brake calipers were cleaned using steam, and were then hand polished and coated with CarPro's DLUX coating, as were the wheels. Carpeted wheel well liners were also coated using CQuartz Fabric to ensure easy cleaning.

With the car back on the ground, attention was turned to another bit of evidence left behind by the previous 'detailing,' a bit of residue in the seam around the rear window.

Once again, steam was employed to dissolve and rinse away the hardened residue:

Finally, with all of the intricate cleaning tasks out of the way, it was time to start correcting the paint. Up first, the pillar on the roof panel:

The first round of compounding made a significant improvement, but a few more passes would be needed to fully restore the finish to pristine condition.

Much better:

The rear hatch also had a number of issues:

The trunk spoiler showed more evidence of straight line wash induced scratches, which took three rounds of compounding to address:

While working my way around the car, I encountered another disturbing factory issue, which unfortunately affected several areas on the car (and has been reported to be common among early C7s):

In this photo, you can see that a mottled, tan shadow is visible through the paint near the window belt molding. This is indicative of insufficient coverage of base-coat when the car was painted at the factory (in other words, primer can be seen through the paint). There was already one area that appeared to have been carelessly burned through either at the factory, or during the dealer prep.

Similar thin spots were also present on the outer edge of the door on both sides of the car, as well as the underside of the rear fascia. In order to prevent doing any more damage, the thin edges were masked off during compounding to prevent excessive material removal:

The only way to repair this condition would be to refinish the entire affected body panels; something this owner was looking to avoid since keeping the car's originality intact was important to him (in 20-30 years' time, if this car were entered into NCRS judging, having these factory issues could actually improve its scoring).

Moving on to the front of the car, the hood was found to be particularly worn with signs of scuffing and deep scratches which also took several passes of heavy compounding to remove:

With many hours of heavy compounding completed, the car was left looking a bit dusty, with paint and abrasive residue deposited all over the car and in every body seam.

Because this dust can easily damage the finish if simply wiped off with a towel, the car was pulled back outside and rinsed/dried to safely flush it away. Final polishing was then carried out, resulting in massively improved gloss, depth, and clarity:

In order to protect the finish and make subsequent maintenance easier, the remainder of the car was coated with CQuartz Finest; incidentally this also added even further gloss to the finish. This Stingray now looks its best, and should stay that way for the long run.
