After hearing about Gibbs Brand metal protector used on bare metal cars for years, I decided to get some to try on Hawkeye and Hot Rod Pat's bare metal '53 Chevy. They'd been using WD-40 on it, but it doesn't last all that long, and dust sticks to it. Since they're off at college, I decided to do a head to head comparison with the WD-40 and the Gibbs. I welded a hoop to a piece of sheetmetal, sanded the whole thing with a DA, cleaned it with brake cleaner, then sprayed half with WD-40, and half with Gibbs. To accelorate my test, I hung it in my shower. Once a day, I'd briefly run it under the water and hang it back up. After only a week, I had rust starting to form. To my utter shock, the GIBBS SIDE started rusting first. What the heck? I thought this stuff was supposed to be the best stuff ever, and fully expected it to far outlast the WD-40?!? And yet, it started rusting before even lowley WD-40. What are your thoughts on this? *note: In the pic, the left side is WD-40, the right is Gibbs. You can see the bright newly formed rust spots on the metal.
