: . . .The final polished bars had different polishes on them and
: the finist looked like a brilliant mirror and when observed under the
: microscope all you seen was the pores of the iron and no scratches. . .

Now take all those nicely polished steel bars and throw them into the water, preferably in such a way that they bounce off a few rocks. If they don't get nicked, they'll rust.

I know that was a violent and traumatic thing I jsut asked you to do, so when you can breathe again, remember that your boat is going to be thrown into the water and occasionally hit some untamed abrasives. It is a boat, not a shaving mirror. Unless you intend to use it as a mold or plug, you're wasting paddling time by putting a killer shine on a boat's hull.

Sanding is a pain. Let it go for a while and go play with the boat. At the end of the season you can sand and varnish again.
