I need some advice. My car bonnet won't stay locked down properly. My car mechanic friend says it's a common problem and I need to spray some WD40 on it sharpish or it might fly up in my face when I'm driving and I'll crash into a ditch. Unfortunately I'm not the handiest of modern girls and WD40 isn't something I keep in stock (I also tend to use tweezers or knives instead of screwdrivers etc). So what I need to know is does anyone know what I could use instead given the typical contents of a cupboard under the sink and a bathroom cabinet?
