Fella, Patina is a fancy word for wear and tear. If the tank was all original but knocked about from use then I'd absolutely leave it, however it's an old non original gold star tank with horribly applied shitty filler holding in some awful bolt stuck in there to fill the hole. It's all falling out, it's not cool or full of character, it's just a shite job
With the greatest of respect to all that have decided that it would be better left alone, none have you have seen it in the flesh. Of the 15 or so people that have seen the bike, actually been here and seen it they have all without exception agreed when I've told them of my plans to paint it.
Right .... Off my soapbox!
