Shelf life of PEA / Regane / Techron?

[Chuck1986]

I have a couple bottles of Gumout Regane that were purchased about 1.5 or 2 years ago. They're unopened and I haven't had to use them cuz I feel like regular Lucas UCL treatments have been doing such a great job.

Anyone know how long PEA (polyether amine), the active ingredient, stays good for?

I would ask Gumout.

I would guess they are OK, but I would also guess beyond two years would be too long.

I would think as long as the seal isn't broken on the spout then it should be fine. It not like it pills/medicaation that canpoil over time. Besides that can you imagine how long a new bottle one buys over the shelve it's been setting in the warehouse before it trucked to store nation-wide?
