As an alternative, find a local spray
shop or paint trade supplier. They should mix you up a touch up pot for very little money. They'll just need your paint code, its on the
sticker in the boot under the carpet.
I had a pot made up for mine, comes with a brush in the lid, only cost me a tenner, and its plenty, far more than i needed really.
I used Colourtone in Stockport.
