Assessing the Current Condition

• Exterior: Inspect the body for rust, dents, and overall condition. Check the paint, chrome trim, and glass. Rust is a common enemy, so pay close attention to areas like the rocker panels, wheel wells, and trunk floor.
• Interior: Evaluate the condition of the seats, headliner, dashboard, and carpets. Check for tears, fading, and wear. Inspect the gauges, lights, and other interior components.
• Mechanical: Assess the engine, transmission, brakes, and suspension. Check for leaks, unusual noises, and overall functionality. A compression test can provide valuable insight into the engine's health.

Setting Realistic Goals and Budgeting

Restoration projects can quickly become expensive.

• Define Your Goals: Decide what level of restoration you want. Are you aiming for a concourse-quality restoration, a driver-quality restoration, or something in between? This will influence your budget and the scope of work.
• Budgeting: Create a detailed budget that includes the cost of parts, materials, tools, and potential labor costs. Set aside extra funds for unexpected expenses. Our analysis indicates that a full restoration can range from several thousand to tens of thousands of dollars, depending on the extent of work needed.
• Timeline: Estimate the time required for each phase of the project. Restoration can take months or even years, so be patient.

2. Disassembly and Preparation

Once you have a plan, it's time to disassemble the car. This is a critical stage where you meticulously remove components, label parts, and prepare the body for repair.

Disassembly Process

• Document Everything: Take photos and videos during disassembly. Label all parts clearly and keep them organized. Consider using a parts storage system (bins, bags, etc.)
• Exterior Disassembly: Remove all exterior trim, lights, bumpers, and glass. Be careful not to damage parts you plan to reuse.
• Interior Disassembly: Remove the seats, carpets, headliner, dashboard, and door panels. Label wiring harnesses and connectors.
• Mechanical Disassembly: Drain fluids, remove the engine, transmission, and suspension components. Disconnect all wiring and hoses. Document all the mechanical components and their locations.

Bodywork and Rust Repair

Rust repair is often the most time-consuming and challenging part of a restoration. Our team has learned that rust can spread, so quick action is the best.

• Rust Removal: Remove rust using methods like media blasting, chemical stripping, or mechanical grinding. Ensure all rust is removed to prevent it from returning.
• Metal Fabrication: Repair or replace rusted panels. Welding skills are often required. You can purchase replacement panels or fabricate your own.
• Bodywork: Repair dents, smooth out imperfections, and prepare the body for paint. This involves using body filler, sanding, and priming.

3. Engine and Mechanical Restoration

The engine and mechanical components are the heart of your Cutlass Supreme. Restoring these systems will ensure your car runs and drives reliably.

Engine Rebuild

A quality paint job can make your Cutlass Supreme look new again.

Paint Preparation

Painting Process
