Has anyone had experience of using Simoniz VHT aerosol paint on engine casings? I used it on the clutch cover, final drive sprocket/starter motor cover and alternator cover on my CB400F. The instructions on the tin say to cure the paint by baking in an oven for up to 1 1/2 hours and up to 220 degrees c. I was a bit wary of getting the aluminium too hot and it distorting so I only heated it to about 150 degrees. I was quite pleased with the finish and colour, but the paint still seems quite soft and had no resistance to petrol at all when some dripped on it from a dodgy petrol tap connection. Is it ok to heat aluminium castings to 220 degrees, or would baking for longer compensate for the lower temperature, or should I find some other way of refinishing the casing?. Some people have suggested having them polished, but I don't really fancy that. Any thoughts greatly appreciated. With thanks, Roger.
