A tale of two Stingrays Pt. 2: 1964 Convertible

February 26, 1964; a significant date in history. In London, The Beatles were recording the soundtrack for their first feature film, "A Hard Day's Night," at Abbey Road studio. Recently crowned world heavyweight boxer Cassius Clay publicly adopted the name Muhammad Ali. More importantly on this Wednesday, the 6,921st Corvette Convertible rolled off the assembly line in St. Louis, MO wearing stately satin silver paint wrapped around a blue vinyl interior. The car was destined for New York, where it would spend its first four decades.

Fast forward to the late 1990s, when the car (by now in rough condition due to age and lack of care) was obtained by the current owner and transported to Michigan. Upon arrival, it underwent an extensive frame-off, nut-and-bolt restoration. During this time, the car was refinished in silver-blue, another factory available color during the 1964 model year. Since that time, it has been enjoyed at many cruise-ins and car shows; and that is where our story begins.

In March of 2014, this 'Sting Ray' along with its 50 year newer counterpart (featured in part one of this saga) were on display at the Detroit Autorama. By that point, age had started to take its toll on the restoration, and some areas of the paint were left looking a bit dull. The car's owner approached a representative working in the Meguiar's booth to inquire as to how the paint could be improved upon; this turned out to be none other than Michael Stoops, Internet Technical Manager, Meguiar's Online forum administrator, and highly skilled Car Crazy detailer. Mike offered to see what he could do on the worst areas of the finish on the spot, so the car could make a good showing.

Knowing that the car would need more extensive attention at a later date to truly bring the finish back to its full potential, Mike also agreed to refer the owner to a local professional to complete the remaining work. I was in attendance at the show that year (also having the opportunity to work with Mike on another special project, an emergency makeover on a highly customized Mustang II: Emergency Makeover: Detroit Autorama Edition with Michael Stoops), and Mike showed this car to me while I was there.

A few months after the show, I received a call asking for my opinion about what these cars would need. The owner indicated that he would be taking the '64 back to his painter to have a few areas refinished as there were several rock chips in need of attention first. This spring I received word that the cars were finally ready to be completed.

As was the case with the C7, I initially inspected this car in the client's garage to fully gauge its condition. The inspection revealed a number of issues ranging from cracks in the paint and fiberglass bodywork, to "mapped through" defects, to paintwork shrinkage due to age:

A few weeks later, the car arrived at my shop following completion of the C7 from part 1:

A closer look under my controlled lighting reveals a clearer look at our starting point, from DA pigtails in the body work to shrinkage and haze in the topcoats:

Before beginning the paint correction duties, attention was turned to cleaning and conditioning of other components. First, all of the gaskets and weather seals around the doors and windows were cleaned and protected with Meguiar's Natural Shine. It is vital, especially on an older car such as this one, to maintain these rubber parts with a water-based dressing to keep them moist and supple in order to prevent degradation over time.

Next, attention would turn to the wide white-wall tires. These were also beginning to show their age, with brown, oxidized rubber on the sidewalls and yellowing of the white stripe:

Using old-stock Westley's Bleache-White cleaner and a toothbrush, the tires were carefully cleaned and rinsed with steam:

Before we get into the paint correction work, let's take a moment to talk about supplies. Since the paint shrinkage and other textural issues with the finish would require wet sanding to complete, a selection of papers and sanding discs were assembled, along with a few other tools. For abrasives, the Meguiar's Unigrit line is by far one of the best in the business; providing uniform, even results that would be easy to polish back to gloss. Accompanying these were a set of custom hard sanding blocks, hand-made for me by Jason Killmer of JKAutomotive Detailing. For those who haven't heard of Jason, he is known as one of the foremost experts in sanding and finishing among high end hot rod and custom car builders, having worked on several multi-million dollar builds including Riddler award winners. His knowledge and advice were extremely helpful in successfully completing this job.

Also handy to keep on hand were an ultrasonic paint thickness gauge to assist in determining where any thin areas were on the car, as well as standard single edge razor blades to "shave" runs in the finish (don't try this at home, folks!):

For more intricate, curved areas, I also utilized an X-Acto knife with a #10 blade. The curvature of the blade made it easy to get into tight spots without digging a sharp edge into the finish and causing unnecessary damage.

As you can see, once the shaving marks were compounded out, no sign of the run remains:

With the runs fully addressed, it was time to move on to other areas of concern. First up was an area on the upper portion of the door and top lid. There was indentation damage caused by the friction and pressure of the convertible top seals:

Thanfully this damage wasn't too deep, and could be sanded mostly level with 2000-grit:

The remainder of the car was primarily plagued with fairly uniform shrinkage, which was leveled by hand using 2500-grit paper:

Another unique challenge posed by this car was that it had been repaired a number of times since the initial restoration with mid-panel clear coat blends. When sanding, some of these blend areas became "exposed," as seen in this shot on the top of the right fender:

This meant great care had to be taken not to further disturb the blends during the compounding and polishing phase. All of the blend areas would be compounded with a rotary (as the force of a DA polisher could prove too violent) and a water-soluble compound would be chosen for the ability to more easily regulate heat buildup during each working cycle. Eventually, the entire car was completely and successfully compounded:

A quick final polishing step would maximize the gloss and clarity of the finish, after which it was time to bathe the car with two coats of CQuartz Finest in order to protect the finish for the long haul:

Once the car was fully coated, an Infrared heat lamp was used for curing:

The result of this effort was a refined, refreshed, and truly gorgeous classic, ready to show off its Bill Mitchell-penned lines proudly.
