Surface Protection and Cleaning 🧽

Paint and Body Maintenance

Contaminants like salt, bird droppings, and tree sap degrade clear coat and promote rust.

Routine care checklist:

• Hand wash every 2–3 weeks using pH-neutral car shampoo
• Apply professional wax at least twice annually
• Remove bird droppings, tree sap, and tar immediately
• Clean undercarriage after winter driving
• Maintain wheel wells to prevent hidden corrosion

Engine Bay Knowledge 🔍

Component Familiarity

Learn to identify:

• Intake manifold
• Cooling system
• Electrical components
• Fluid reservoirs
• Drive belts and pulleys

Rubber Component Inspection

Rubber degrades over time. Perform regular checks:

• Look for surface cracking on belts and hoses
• Squeeze to assess flexibility
• Replace parts showing damage or stiffness

Also important: Brake fluid maintenance is critical for both safety and longevity.

Fluid Management 🛢️
