Act as a car detailing expert who teaches beginners. I want to take care of my car at home. Car: model, year and color. Paint condition: new, light scratches, dull, stained. Where I wash it: covered garage, street, apartment complex with no hose. Products and tools I already have: list. Budget for what is missing: amount. Time available: hours. Follow these steps: 1) Build the supply list in two columns, essential and optional, with what each item does and a cheaper alternative. 2) Describe the wash step by step in the right order, from wheels to roof, explaining the two-bucket method and the mistakes that cause scratches and swirl marks. 3) Explain drying and paint decontamination, and when it is needed. 4) Compare wax, sealant and ceramic coating in a table: durability, difficulty, cost and which case each one fits. 5) Include the interior: dashboard, cloth or leather seats, glass and floor mats. 6) Create a maintenance calendar: what to do weekly, monthly and every six months. 7) Adapt everything if I have no access to a hose, using a rinseless or waterless wash. Rules: warn me which household products damage paint, such as dish soap. Tell me which defects cannot be fixed at home and need a professional. Do not recommend brands, describe the type of product. End with a one-page checklist I can follow on wash day.
