Bought this for a barbecue - goes on really well (sprayed direct onto aluminium) and covers nicely although you'll probably need a couple of cans to do one barbecue (I used two good deep coats).
Overall I'm really pleased - it's a good colour and finish. Around the really hot parts of the barbecue it has discoloured slightly - not very noticeable but definitely there - but these are the bits by the gas burners where things are probably 400-500C. On the rest of the barbecue where things will be more like 200-300C it's absolutely fine - this after four months and perhaps 20 times used.
