After the restoration of my Monte Carlo also removed the Vynil roof, of course I found rust again… not very much, but in some places it has already gone a little deeper into the sheet metal. After the sheet metal on the roof is already so thin and easy to press, I was definitely advised from sandblasting, otherwise the whole roof can become wavy. A friend said that I should treat everything with Fertan, then wash it off and 2 times with Brunox Epoxy Does anyone have experience with the stuff or any other idea??? Thank you! Greeting Daniel
