Short answer
Water spots range from removable mineral deposits to etching that has altered the clear coat. Start with the least aggressive method: wash, controlled mineral removal, then polishing only if the defect is actually in the paint.
What matters in Hawaiʻi
Acidic spot removers are professional tools, not universal fixes. They require surface compatibility, short dwell times, thorough rinsing and personal protection. A water-softening or deionized-rinse setup can reduce new mineral deposits but does not repair existing etching.
Outdoor parking, intense UV, coastal salt, humidity and frequent sand or soil exposure can shorten maintenance intervals. The correct interval depends on where the vehicle lives and how often it is driven.
What to ask a detailer
Ask what process they recommend, what result is realistic, what could be damaged by an overly aggressive approach, and what maintenance is required afterward. For specialty work, confirm the provider has experience with the exact finish or problem on your vehicle.
