50. Protect Boats from Corrosion
Discovering new WD-40 uses is always a treat, especially when it helps protect your prized boat from salt water’s harsh embrace. A quick spray on the stern after each voyage acts like a shield, warding off corrosion and keeping your vessel in tip-top shape.
It’s a small step that packs a big punch in maintaining your boat’s gleaming appearance, reminiscent of its first day with you. Not only does it keep parts from wearing out prematurely, but it also preserves that just-bought shine for ages.
