What? Another post about actual modeling? No way! Yes, way!
Wet sanding: I’ve general just dry sanded when I’ve modeled. However, after many, many years I have been won over to wet sanding. It doesn’t take much water, just enough to wet the sandpaper. It makes a bit more of a mess, but it really makes a difference in regard to the ultimate quality of the finish. Also, in regard to sanding, I love the Flex-i-file and use them constantly, but I find that they work much better for me if I split the sanding tapes laterally in half. The other key is not to try and make them last too long. Like X-Acto blades, change often.
