Spraypainting dos and don'ts

After spraypainting a few things, I made the following observations... ;-)

Places like Home Depot sell spray paint in larger cans, for much less than HobbyTown. (E.g. $3 for a large can vs $5 for a small one)

However... this kind of paint isn't very suitable for Zoids, or other projects with small parts that move or need to fit into each other. I sprayed my old Playstation with it, which was fine; using it on a small Zoid pretty much ruined it, though.

If you have to spray a lot of small pieces, it's a good idea to place them all close together on a newspaper, spray the whole shebang, turn them over, and spray again. It sure beats holding them in your hand one by one and spraying them that way.
