That's besides the point though. The transfer of dye from the fabric onto the figure therefore staining it pretty much forever in any capacity shouldn't be happening in the first place.
However, the point was comparing how ppl seem to have an issue with whatever longevity notice JND has put out about the silicone, yet HT more than likely knows of this as an issue but has yet to do anything about it; nor have they ever once (to my knowledge) publicly acknowledged the dye or pleather deterioration as an issue and made a warning about it in the way JND has about their silicone. The only figure that I can remember (though I'm happy to be corrected) that HT sort of made an effort was The Wolverine where they gave him an additonal long sleeve undershirt to mitigate the staining of the black shirt onto the muscle body and possibly put a notice in the instructions. But, you'd still get staining on the neck from the shirt collar so it wasn't 100% preventative.
As for wrapping a silicone body in plastic, so far it doesn't seem to have had any sort of negative reaction when doing so with any Phicen/TBLeague bodies I've used as far as using something like plastic wrap like one might use with food.
That's all guessing and hypotheticals though. You could say that and then someone else could say the exact opposite which I recently saw in the FB JND Collector's group when this came up. Someone mentioned they still have a silicone doll from the 70s that looks brand new. Really, anyone can say anything and we really won't know until the time comes. At the end of the day, none of us will know until either the first person posts about their issues X amount of days/months/years later or after 30 years and some folks still have pristine statues/figures.
Agreed. I mentioned something similar in the JND Geralt thread. Glued on hair will dry out and deteriorate and you'll need to have the sculpts rehaired. Though, admittedly, it's theoretically easier to get a sculpt rehaired than getting a whole silicone sculpt replaced. But, as you mentioned, nothing lasts forever so I guess it's a choice to enjoy something for as long as it does last rather than ultimately waiting for the worst to happen.
At the end of the day, it's ultimately up to the collector to do what's right for them, their budget and their collection.
