When working on a classic model, the first step is proper planning and organizing the parts chronologically. Creating documentation and keeping old photos and technical schematics handy makes the process much smoother. When dealing with corrosion, it's helpful to clean steel components first (instead of aluminum) and apply rust remover and primer. Measuring accessories like belts and cables again is critical to ensure the right tolerances. For projects like yours, which stages do you prioritize? I'd love to hear about your experiences.

In practice, my top priority is always to conduct a thorough assessment of the chassis and subframe. Before even touching any visible parts, I perform a detailed inspection—checking welds, measuring geometry deviations, and identifying corroded areas. This step prevents me from discovering structural defects later that could compromise the entire restoration. I use a tracking sheet where each inspection point is logged, ensuring that subsequent decisions (disassembly, treatment, replacement) are based on concrete data rather than visual impressions.
When it comes to corrosion, I’ve found that treating steel components first—even those covered by aluminum—simplifies the process. I start by applying a zinc phosphate-based stripper to steel surfaces, followed by a high-adhesion anti-rust primer. Once the treatment is dry, I move on to aluminum parts: cleaning them with a neutral solution and then protecting them with anodized coating or specialized aluminum paint. This sequence minimizes cross-contamination risks and ensures better longevity for the treatments.
Finally, I prioritize adjusting belts, cables, and levers right after the first bodywork pass, as these components require very precise tolerances. I measure them with depth gauges and compare the dimensions to the original blueprints, making adjustments as needed. Personally, I prefer to finalize the engine and transmission before applying the final paint, which gives me a clear view of the vehicle’s weight and center of gravity while saving time on sanding if mechanical adjustments are still necessary.
What’s your take on the priority between the chassis and the powertrain?
Same here, I always create a "timeline" before any restoration; especially with 60-70s Fiat and Alfa models, cleaning the steel body part is the most critical step. After battling corrosion by scraping the steel parts with a pressure washer brush and sea shell powder, I apply a zinc phosphate primer; this delays rusting on aluminum parts due to the zinc coating.
I think after finishing chassis and suspension measurements, the best way is to straighten the body panel and collect the bodywork molds in a photo file. Re-measuring cables and belts, checking tolerances is one of the last steps; this way you don’t face any surprises during assembly. Bro, if your project follows the same order, the toughest part will be dealing with corrosion in the steel; so, definitely spend extra time on the rust remover and primer stages. Honestly, following these steps makes the project go much smoother.
