hihihi...thank you, Bill!!
Well, you should be a good teacher, though! The guide is so clear and you even answered all possible questions that might pop up in my head. haha ......

Thanks again Bill, I would try it out soon. But the problem is that it's not just a small spot of corrosion. I got the whole area rusted . And that will take a long time for paint to dry out if I decide to spray paint it...hic hic.
