If anyone in sydney is after galmet paint in sydney I found a place in rockdale that stocks it and will tint it to the correct color I had some mixed up today and its almost an identical match to the bottom of my fuel tank and it only cost $35 for 1L from the dulux paint shop
409 Princes Hwy Rockdale
The only thing was they didnt know the formula but I got that after calling galmet and it is ss27 to 1L of gunmetal hammertone
