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. |

From the Por-15 Tech sheet: POR-15® Rust Preventive Coating is designed for application directly on rusted, sandblasted, and seasoned metal surfaces. It could be more clear. What is seasoned metal? From my experience, if you don't have rust pitting, or any tooth in the metal, POR-15 won't adhere well. If the area is rusted, then it adheres just fine. One thing you can do, if you have an area that has been weakened by rust pitting on one side, but not enough to warrant cutting it out - Put down a coat of POR-15, then lay down some fiberglass cloth, and fill the cloth with POR-15. This is very strong. |
