Does TIM go bad? e.g. maybe it dries out a little and maybe not work as good?
Like it get thicker and not as good.
I feel like it must but wondering thoughts of others..
In an airtight completely sealed environment, It would probably be fine for a long time. But it does dry out eventually. I recently found a ~10 year old tube that was hard as a rock. I have a couple opened tubes from around 3-5 years ago that seem a little thicker than I remember them being initially, but are still probably fine. IDK how much the newer stuff has improved though. I will let you know in 10 years how well the thermal grizzly stuff holds up
