The thread on older kits reminded me of something. I have a 1:48 scale Viggen kit that's about 20 years old and I plan to build. The thing is the plastic has yellowed a little ( nothing compared to a friend's Tyderium shuttle, which was molded in light gray and now about the same color as Model Master's FS Dark Tan ). What causes this and do I need to take any special precautions when I do get around to building it?
I couldn't even find my way back to "normal" with the Hubble!
