The FDM printing process creates a layered texture. While these layers provide industrial strength, they require specific cleaning techniques to maintain their appearance.

• Mild Detergents: Clean parts using warm water and mild dish soap. This effectively removes road grime and dust without degrading the polymer.
• Soft Brushes: Use a soft-bristled brush to gently clean between the layer lines. Avoid abrasive scouring pads, which can dull the surface finish.
• Chemical Warning: Do not use Acetone or high-strength industrial degreasers. These solvents can chemically attack PETG, causing surface clouding or structural softening.

PETG is engineered for high-heat environments, but peak Australian summer temperatures in closed vehicles can be extreme.

• Heat Ceiling: PETG remains structurally stable up to approximately 80°C. In most cabin environments, the material will maintain its shape perfectly.
• Ventilation: When storing a vehicle for extended periods in direct sun, crack a vent or window to keep internal temperatures below the material's glass transition point.

• Vibration Check: Corrugated roads and engine vibrations can loosen fittings over time. Inspect mounting screws every 5,000km to ensure they remain firm.
• Fastening: When mounting parts, tighten until firm. Avoid over-torquing, as excessive pressure on a single point can eventually lead to fatigue in the polymer structure.
• Damping: The use of small rubber washers between the printed part and the vehicle body is recommended to absorb high-frequency road vibrations.
