Paint, adhesives, and sealants are the "skin" of everything around you — coating a bridge so it won't rot, keeping a car from rusting, holding an entire EV together without welding steel. We barely notice them, but without them, our buildings, cars, ships, and phones would fall apart many times faster than you'd think. This is a ~$300 billion business that turns "cheap stuff in a drum" into an "expensive brand in a can" — and the EV and construction waves are quietly pushing it to grow.
