This is interesting information, thank you! I find the steel wool to sandpaper equivalent values interesting and wonder how they arrived at those. I've used 000 steel wool on my truck before and for the most part, the 000 steel wool was fairly gentle. If I were to hit the paint with the equivalent 280 grit sandpaper I know I would burn through the paint in an instant.
For reference, here is the front fender on my old truck after hitting it with 000 steel wool. This is OG paint that was buffed to a mirror shine. It was too shiny for me so I dulled it back down with the steel wool.
