Using old Wet Diamond sealant

I have a half finished bottle of wet diamond liquid paint sealant from about 4 years ago...Tried using it today and it came out all thin and liquidity. Tried shaking it up a bit and starting to thicken. Wondering whether worth it to keep trying to make it usable, or inevitably need to trash it at this point?

Thanks for any help!

If it remains separated after shaking, trash it.

Try putting a small ball bearing or nut in the bottle. It should help with the mixing. Wet Diamond is notorious for separating. You really have to SHAKE IT !!!

Shelf life on that specific product has disappointed me.
