I could damn near write a book! I collect old electronic test equipment & computers, as well as old processors/chips. So quite a bit of that. Tools-wise I have quite a few, my favorite few being my great great grandfather’s tap & die set (early 1900s), my 1985 Bridgeport R2E4 C/NC milling machine that I’m restoring, and my 1954 Sheldon lathe!

No, the difference is just that spots on the hood don’t tend to grow much, especially if they’ve been covered with touch up paint. The most common parts of a car to rust is anything on the underbody, and I’d say the most common body panels to rust are right near the fenders usually because that’s where rocks get kicked up, break through the paint, and when water sits in there it rusts. Super common, just a fact of life.

The paint should act as the sealer as long as you touch it up if it ever gets knocked off again. Little rust spots on what I assume to be the hood or front of your car are really a non-issue, corrosion-wise. But that said, are these just small spots on body panels, or are they spots near wheel wells or something where water tends to collect?
