New OEM (factory) degas bottles are still available (aka coolant bottle)

But they are not cheap. My dealer discount was $283 plus tax.

Don't know how many are available.

I would hope that by being in a box... there would be no UV breakdown.

I'll look for a manufacturing date.

So it was boxed... Couldn't find a manufactured date. (shrug).
