Epoxy/polyster putty tutorial??

Are there any in the FAQs? If not can someone put one together for me? I would like to know how to use them and for what application they are used for. Thanks!!!

epoxy two part putty: take equal amounts of each stick, mix it together really well(wet fingers works well), and apply it. i would use it for building body kits, scratchbuilding, etc.... most epoxy putties have long working time.
