Dinitrol 958

[pgeorgeson]

Following up on prior questions. I am restoring a 1970 911T that has its original undercoating, which is generally in good shape. There is grime and some overspray on it. I am having it dry ice blasted, but am not sure if that will get the overspray off. I am not going to remove the existing original undercoat. If I can’t get all the overspray off, the blaster is recommending spraying the whole undercarriage with Dinitrol 958. The other option I was considering was a light spay of Wurth over the existing undercoat.
Does anyone have experience or (informed) opinions about spraying with Dinitrol versus Wurth?
