Found poundland are selling spray paints - both the gold, as pictured, as well as silver and grey. 250/300ml sizes.
Great for crafts (dare I say Christmas) and giving your furniture a new lease of life.
The gold is a generic spray paint, though the silver is marked as a 'silver wheel' spray but this did a fantastic job for crafts for me - and hey surely it's hard wearing. The grey is a 'wheel primer' - I've used plenty of primer sprays in my up cycling before and they look fantastic as a final colour though I haven't tested this one.
Available in the DIY section next to all other car bits and pieces, should be nationwide.
Spray paints usually retail for at least £5 so this is a great deal for the limited selection.
