Well I see this yellowing could go on forever The one thing we all need to remember here is to take great care of your things, expecially those that are costly!! My jetfire that I bought WAYYYYY back in the mid 80's is still like new. This is due to me not handling it all the time and keeping it clean, I think I only transformed this once. Come to think of it all my things are like that. Oh well, seems we all agree on that
