So, does Future yellow over time, or what?

I have one model that I sprayed with Future about two-3 years ago, a King Tiger, and as far as I can tell, it has not yellowed, with the caveat that yellowing on German 3-color camo is probably not easily noticed. 

Swanny states in The Complete Future that he has examined a number of models where Future was used and yellowing occurred, and found in every case that it was the paint underneath that had discolored.  You'll have to search for it on that page, I'm not sure where that section is located, but it's an informative read.

I've been using it for about four years. A good friend and better modeler has been using it for about ten years. If the stuff yellows I sure can't tell it.
I think the above comments are right, that the underlying paint can change it. Especially if the paint was not allowed to completely cure before it was applied.

Future has additives in it to prevent yellowing from UV light. Think how happy a homeowner (wife) would be if the floors turned yellow after application.

Models that do turn yellow is from one of three reasons...prolonged direct exposure to UV light....reaction from paint exposed to UV (most hobby paints do not have any UV protection additives)....and nicotine from having a smoker in the dwelling.

All clear coats, even Future, will yellow given enough time. UV radiation is unstoppable, and can only be slowed. Future do contain UV inhibitors, but they are short term use only. Most kitchens get cleaned and have Future re-applied long before any yellowing can occur.

I have models that are going on 10 years old with no sign of yellowing of the Future top coat.  However I have several that were top coated with Testors Gloss Cote that have yellowed significantly.  All are stored the same way & UV protected as much as possible.

I have Futured canopies from the mid 's that are crystal clear.
