A maintenance product cannot compensate for contamination trapped underneath it. Before applying coating wax or a maintenance spray, wash thoroughly and assess whether mineral deposits, bonded dirt, or old residue require additional cleaning.
Working sequence
- Wash and dry the vehicle correctly.
- Inspect under direct light for water spots and embedded contamination.
- Use the least aggressive suitable cleaning method.
- Apply the maintenance product thinly and evenly according to its instructions.
- Buff with clean towels and inspect before adding more product.
