You nailed it—those “quick fixes” are like putting a Band-Aid on a leaky pipe. I’ve seen folks slap on some paint and call it a day, then act shocked when the rust comes back with a vengeance. Zinc primer and rust converter are lifesavers, especially in places where winter likes to play rough. I do agree, though, sometimes you don’t need to go full bare metal if the paint’s still hanging on. But yeah, if there’s even a hint of bubbling, it’s game over. Funny how the shortcut crowd always seems surprised when their “repairs” don’t survive till spring...
That bubbling under the paint is always a red flag for me too. Last spring, after a nasty hailstorm, I thought I could just sand down a couple of dings on my shed roof and slap some touch-up paint on. Looked fine for a few months, but by fall, rust was creeping back in those exact spots. Ended up stripping it back to bare metal, hitting it with rust converter, then zinc primer, and finally repainting. It’s more work up front, but honestly, skipping steps just means you’re doing it all over again sooner than you’d like.
