Putty: Aves, Wave Strong Black CA, Mr Dissolved Putty, and Mr Surfacer 500
Sandpaper: I use cheapo coarse grit for shaping, sanding sticks and film for the finer work.
Primer: When I use it, it's either Mr. Resin Primer or Mr. Surfaer 1200. Used to use Tamiya Fine Primer in the rattle can.
Paint: Tamiya or Gunze. You can extend it a bit with Future if you want a little slower dry time.
Sealer: Testors or Future.
A lot of these need an airbrush. The Mr Surfacer now comes in the can.
