Sometimes, rust stains can be particularly stubborn and require additional techniques:

  • Use Baking Soda Paste: For tough stains, mix baking soda with water to create a paste and apply it directly to the stain. Let it sit for 15 minutes before scrubbing.

Expert Insight: “When dealing with stubborn rust stains on gelcoat, patience and persistence are key. Sometimes multiple applications are necessary.”
