Only F9 beneath?

[SvingenB]

Started polishing yesterday. When I finally got the grip on it, I must say the F9 alone gives a remarkable good result. I was thinking using f9 only beneath, but maybe the C/S contain some other stuff (wax or something) that also is a good thing. What is the common procedure here?

I think it would be fine to only polish with F9 if you were happy enough with it. Other people do a lazy man's polish job where they paint underneath. Same idea, you don't really see it close up. I do notice a big difference between F9 and C though. Have not opened the S yet.

It seems the more you polish with the finer grit, the more the grain is closed and the more resistant the surface becomes to oxidation that tends to turn it white. From factory stock, polish with the "F" grade looks pretty good, but the "C" is that much better, and the "S" really makes for a mirror finish:

The way I tell when it is sufficiently polished is when the hazy image of Joe cool pilot becomes a sharp clear image of an old fart.

:D I think that suits me just perfect. Both the description of sufficiently polished and the lazy man's polish.
