WD-40 Specialist Penetrant is a 400ml spray for seized fixings, stuck parts and rusted joints, made to soak into corrosion quickly. It is listed as safe on metal, alloys, rubber, plastic and most paints, stands up to water, works from -20°C to +90°C, and has a Smart Straw and a 360° valve.

Good to know

• Can I spray it on a hot exhaust? Let the exhaust cool first: the penetrant is rated to +90°C, well below a running exhaust, and a cool part lets it soak in rather than flash off.
• Will it harm the paint or rubber nearby? It is listed as safe on rubber, plastic and most paints, so overspray onto bodywork or bushes is less of a worry; wipe it off anyway once the job is done.
• How do I get it to work well? Wire brush the thread, spray, wait, tap the head, then turn it a little back and forth rather than forcing it one way.

Which one?

For a spray that chills the part as well, the Power Maxed Shock & Unlock – 500ml (SU500SC11); for everyday lubrication after the job, the WD-40 Smart Straw – 300ml (44410/135).
