Lead platelets are an important resource in Pacific Drive: it's a key ingredient to crafting items that will shield both you and your car from radiation in the early game, and even more crucially later onl, it's used for crafting bigger car batteries that can hold more charge. But finding lead platelets in the exclusion zone can be tricky until you know what to look for.
Early on in Pacific Drive, radiation is one of the deadlier anomalies since it spreads across the ground in wide patches, often covering buildings and containers you need to loot. Your car (if all its doors are attached and closed) will give you some protection from radiation, but once you step out your health will be steadily drained inside radioactive anomalies. Radiation will also begin to damage your car if you're in it long enough. That's why lead platelets are so important to find quickly.
