Given this former Cali car is coming up on 50 years and probably not always taken good care of, I am lucky to have this level or rusting. I went after it with Ospho, wire brush and clean rinse. Will be applying POR 15 to this area. Question: my gut tells me the well adhered tar is sound and is not hiding any rusting. |

Por 15 is trash.
You’re on the right track but once it’s all clean then epoxy primer then body color. Por 15 is well marketed junk just like k&n air filters which is another rabbit hole. |

(IMG:style_emoticons/default/agree.gif) I love epoxy paint. Dry ice will actually work in getting the tar off. Convert the rust or better yet sand it off. Then epoxy. It is expensive but I like the dplf epoxy from PPG. |

When blasted a decent profile can be obtained to grip the first layer of primer. Ospho is probably the next best |
