Decide whether the scratch has penetrated the primer, base colour coat, or clear coat before
starting any repair work. Run your fingernail gently over the scratch. Should your nail not catch,
the damage is probably restricted to the clear coat and can be repaired with polishing
chemicals. If your nail catches something, the base coat may be damaged and need touch-up
paint. Deep nail scratches call for expert attention if you see white or grey (primer) or bare
metal. This easy check stops useless work on scratches that home remedies cannot mend.
Additionally, it guides you to choose the appropriate product lighter scratches benefit from
micro-abrasives; deeper ones require filling. Before testing, always thoroughly clean and dry the
area because dust can provide inaccurate results. Any effective repair starts on a solid
foundation of exact evaluation
