Refining the Paint Process for Project Cheap Camaro

As summer progresses, the journey of restoring the Cheap Camaro is hitting significant milestones. After extensive sanding and preparation, the restoration project is poised for its next chapter—a quality paint job. This update chronicles the latest phase of work beautifully encapsulated by practical techniques and lessons learned, making the project closer to its visual completion.

This process saw the Cheap Camaro transition back to my garage after spending ample time at Alliance High School. Students there had been instrumental in aligning the vehicle's panels and starting the intricate process of block sanding. However, now that the school year has ended, it was essential to transport the Camaro back home to take advantage of the upcoming three months of dry weather, ideal for painting.

The Next Layer: Polyester Primer-Surfacer

Previously, I applied a coat of Eastwood Contour Polyester Primer-Surfacer, carefully covering the epoxy-coated body. This polyester product serves multiple purposes; it effectively fills in minor surface imperfections and doesn’t shrink post-application, making it easier to sand down for a flat and smooth finish. The process is less about exerting effort and more about having a steady hand to maintain the desired finesse.

After the students made good progress with the polyester sanding, a few visible thin spots necessitated another application. Reinforcing a coat of poly needed a quick setup—a simple inflatable paint booth in my driveway. The booth required just one blower for inflation and two additional fans for airflow, a setup that proved to be critical, as I ran into electrical challenges mid-application. Fortunately, the primer was dry to the touch before we had any significant issues.

The sanding technique involves applying a dry guide coat, then using 220-grit sandpaper until it disappears, revealing an even finish. After that, a high-grit 320-paper stage is employed to produce an even smoother surface. I found that using various sanding blocks allowed me to adapt to the car’s unique contours, marking a balance between efficiency and thoroughness during this detailed process.

Block sanding largely simplifies the process for flat surfaces, but the Camaro’s curves required creativity. From using Eastwood's Elite Dustless Sanding Blocks to creating personalized rounded blocks with basic paint sticks, I discovered versatility was key. For the tightest spots, I even fashioned tiny two-inch blocks for those hard-to-reach areas, proving there’s no one-size-fits-all solution in this task.

Critical Visual Checks with Panel Check

Upon wrapping up the sanding, I realized that checking the surface visually was imperative for identifying any hidden imperfections. The solution involved applying Panel Check fluid to create a glossy finish that helps illuminate every ding and dent. This reflective surface draws attention to flaws needing correction, which may involve either further sanding or the application of Contour Premium Finishing Glaze designed to fill those smaller blemishes and pinholes.

This iterative process of applying the glaze and sanding until the reflections reveal a flawless surface demands patience, but it’s vital for achieving that show-stopping appearance. I marked any low spots with a graphite pencil for accurate identification during the repair efforts, ensuring nothing gets overlooked.

Transitioning to 2K Urethane Primer

With the polyester work nearing completion, the next logical step is applying a good 2K urethane primer. This choice is crucial, as it provides a smoother base than the thick polyester, filling in the remaining scratches caused by the 320-grit sanding. Achieving a final sand with 600-grit will make the surface ready for sealer and topcoat color.

Following the decision to stick with the Eastwood system, I prepped to apply the 2K Urethane Primer-Surfacer in gray, which would lay down as the foundation before the actual paint. The overall strategy involved breaking the car down into manageable sections and painting parts individually, allowing me to achieve thorough coverage, particularly in the jambs of each component.

Planning for an overcast, moderate-temperature day contributed to an efficient painting session. Before the summer heat intensified, I made sure to remember the previous lessons from earlier paint applications, particularly regarding the importance of cleanliness within the inflatable booth. Dust settling tends to cling to surfaces, so a thorough prep with a leaf blower was performed before introducing the parts back inside.

Each panel underwent cleaning with a wax and grease remover, followed by tack cloth usage to eliminate any remnants of dust. Getting this right is pivotal, motivating me to pay attention to stocking up on the right gear and ensuring the booth is devoid of contamination.

The primer mixes in a 4:1 ratio with an activator and can beneficially include reducer to facilitate a thinner spray. Maintaining the correct gun setup plays a pivotal role—pressure, distance, and technique must be on point, allowing for uniform coverage with a proper fan pattern. I aimed to adopt a 30 psi setting at approximately six inches from the surface, with a 50% overlap during application.

Getting two wet coats on the entire vehicle took roughly half a gallon of primer, with careful attention paid to avoiding distractions that might lead to dust contamination. Having assistance was invaluable during this phase, and with my dad’s help for mixing batches and keeping pace, the operation ran smoothly.

This primer dries quickly, enabling sanding within a few hours. However, I chose to let it sit overnight for peace of mind before moving on to the subsequent sanding phase, using a combination of 320, then 400, and finally 600-grit for the smoothest finish prior to color application.

The summer months are fleeting, leaving a narrow window to complete this part of the project, urging swift yet careful action in these next crucial steps of the restoration into the next stage of the Cheap Camaro project.
