Hello everyone!! The topic doesn’t belong here directly, but you have a lot to do with rust in oldtimers. With my Golf III on the rear wheel runs heavy rust, because I have made the artificial offwheel runs…. Will now everything first with the Flex and after that at a company all sandblasting. So my question: What is best to do now on the blank sheet??? My paintr has something of such a toxic product that would be yellow forblos. Will not just this all it starts to rot again in 1-2 years, since sone laking of the whole car is not cheap. So I need something very good against rust and on it still a good ep-gründer because must be also spachtel and varnisher able. Thanks stefan
