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. |

This thread has become really interesting to see where people draw the DAPO line.
For me DAPO is more or less defined by “solutions” that defy logic - like the photo I posted from my chassis where some idiot (not pulling punches for the sake of kindness) laid in 1/4” of fiberglass and resin to “repair” or conceal a floor pan that needed complete replacement. I knew this to be the case when I bought the car. Unfortunately I’m not so sure about the guy I bought from when he bought it before me. He seemed to believe the car was less rusted than it was but eventually sold it to me at an appropriate price. Where it crosses the line for me into bad behavior is when things are concealed that otherwise should be left exposed for the sake of transparency. Excessive undercoating is a great example of a benign product used by some to intentionally conceal rust, deep pitting, and pin hole perforations. Your definition may vary. |

I agree the DAPO threshold is fuzzy. And I have to admit that some things I did when I was 17 I would now consider extreme DAPO. DAPO might also depend on the value of the car. Or its projected life span. Maybe like porn, DAPO is something you know when you see it. |
