I thought so too. But there is some flaking of the undercoat, so I plan to scrape back to solid adhereing stuff, treat that metal and re-undercoat to protect.
The reality is this car will likely never see a wet road or rain again. But on the other hand as I inspect inch by inch and do what PM is needed, I have no need to tear it totally down, rotisserie it and paint the bottom like a show car. Not a pro, but it is much a solid survivor type car but had a repaint and engine rebuild.
