Future yellowing?

[CaptainHawk1]

I noticed yesterday the Ent A model I Future'd on Friday has yellowed some. What causes this and can it be fixed?

I am a true believer that Future DOES Yellow. I have a bottle and it clearly is NOT clear. I know guys who will debate this with me but this is my belief and I have proof. So IMO Future does yellow. I also have had it crack but I digress...
Now as far as saving your ship. The only thing is to strip off the Future with Amonia or Windex and go again.

I do have a question. Did you paint the Enterprise white by chance?
The reason I ask is that white will also yellow over time depending on the brand and type used.

Was the undercoat acrylic or enamel or lacquer (or tempura? )

Crackling Future I found mostly when glosscoating over a glossy paint. Now I use semi-gloss, even if just a little flat base in the paint.

[CaptainHawk1]

Tamiya Matte White TS-27 spray. If I had used glossy to begin with I wouldn't have sealed it with the Future. I only gloss coated it for the decals. I believe the issue is that I put too much on as I can see areas that were harder to reach that don't have the yellow hint.

Anywhoooo... I'm not killing myself over it. It'll mostly be hidden by the details anyway.

This is what I get for comprehending what I read

I thought this was an older model so it could also have been the white paint.
Since it was only Friday then the paint is not the offender.

How old is your Future? The stuff I have that yellowed in the bottle is at least a decade or more old.

Other then the possibility of chemical contamination (from the pait itself, I suppose), the only thing that could cause yellowing would be sunlight over time, though that's a very short period of time.

It's had absolutely no exposure to the sun as I have been working on it in my garage and I bought the Future 3 weeks ago at a big chain grocer.

I'm not worried about, anyway. Like I said, it's yellowing where it's heavier so I think that has something to do with. My detail work will hide it anyway.

I was just curious.

I heard that if you add a few drops of light blue to the white before spraying, the blue won't be noticable but the white will never yellow over time. Has anyone else heard this?

[CaptainHawk1]

I read this too. It was on the instruction sheet for the aztecking decals I bought for the Excelsior.

Those rattlecans are enamels, IIRC. MAke sure you give them plenty of time before covering with acrylic.

[CaptainHawk1]

Actually. I hadn't put a drop of paint on it in 2 weeks.

I have an almost full bottle of Future that, while in a box, turned into what looks like a bottle of pee.

Yep that is a trick that goes way back.

That's probably not a good thing.
How was it stored - and did you somehow contaminate the contents - pour fluid back in, pipette directly from the container etc?

I have a 5yo bottle with a sqeeze top. Crystal clear!
