What is the most common irritation when working on your cars? For me it is undoing body screws and watching them roll off the workbench onto the floor never to be seen again until you ferret through the dust in the vacuum cleaner.

Here is my solution - magnetic insulation tape attached to your work surface:
       

You could use the magnets removed from your cars but tape covers a larger area so is more likely to catch the errant screws and other metal bits. I found mine in the craft section at Poundland but other stores like The Range and Hobbycraft also do it.
