A dental pick will help you scrape paint off a surface that will be glued. Washing small plastic parts and soaking decals require small plastic conatiners. Tweezers come in handy for adjusting and applying decals. The basic modeling materials include paints, brushes and glues. Additional materials that will help you produce a detailed model include sandpaper, files and filler.
Rubber bands can hold parts together while glueing.
Many other common materials and tools not mentioned here can also be used while constructing a scale model. The table should have enough area to accomodate all the necessary tools and your model. The area should also be covered with a drop cloth or newspaper to aid in cleanup. Lighting above the table should be bright and a small table lamp is an added plus. The tools you will be using should be easly accessible, clean and in good condition.
