Filling seams on aircraft noses. Please help!

still pretty great!

Let me rephrase my answer slightly. Steel wool works fine for very fine sanding. If you have much material to remove you would be better off starting with some coarser sandpaper (something along the lines of 400 to 600 grit) and then progressing towards finer grits. 0000 steel wool is pretty fine and. Finish up with the steel wool if desired for final smoothing.

great

Do you mean can you "Use" 0000 steel wool? If so, yes it works very well. I use it quite a bit.

Could I pass 0000 steel wool as sandpaper?

This helps me out a lot. Thanks.

The detail going away is a common problem but the technique desribed in the link above prevents a lot of damage. If it is panel lines just rescribe them. If it's dimples for rivets deepen them with a tiny drill or the tip of an X-Acto knife before you start to sand. Deepening the panel lines before sanding is also a good idea. Other kinds of detail you'll just have to repair as best as you can.
