What is the best steel wool size for final scuffing before primer? I did all my seam sanding, I would like to use something that can get into every crease, fold, and bend.

Jon I use 2 different grades of Steel Wool to help remove casting imperfections from Metal Diecast. First #3 and finally #OOOO.

I wouldn't use Steel Wool for Plastic. Instead you can use the Green ScotchBrite to scuff the surface of your Plastic in prep for good paint adhesion.

I've tried steel wool and looked at the results under magnification. It's pretty good, but I'm much more impressed with the results of scrubbing with Comet or other abrasive cleanser and an old toothbrush. Steel wool (or Scotch-Brite) will still miss some of the tight crevices next to chrome trim, door handles, etc, but Comet and a brush will get into EVERYTHING. It also gets any hand grease or mold lubricant off. Also, steel wool is usually coated with a fine oil that prevents rust, and the oil can transfer to the surface of a model and lead to fisheyes.
