The WD-40 Specialist Penetrant Aerosol Spray is a high-performance penetrating lubricant designed to rapidly release seized, corroded or rusted fixings and components. Working on contact, this specialist formula saturates deep into seams, crevices and threads to break down rust bonds that hold parts together, quickly freeing stuck nuts, bolts and fixings. This penetrant spray is ideal for maintenance and repair work where components have become seized through corrosion or long-term exposure to the elements. The formula rapidly lubricates seized parts whilst providing excellent water resistance to protect against moisture ingress. Once applied, it leaves behind a protective barrier that helps prevent rust and corrosion from reforming, making it suitable for both immediate repair tasks and longer-term protection of vulnerable components. The 400ml aerosol format delivers precise application, allowing tradespeople and mechanics to target specific areas without waste. The penetrant's deep-penetrating action makes it particularly effective for automotive repairs, machinery maintenance and general engineering applications where conventional lubricants may struggle to reach between tightly bonded surfaces.
