How long does Optimum Poli-Seal AIO last?

[Coyote33]

I have looked at the listings for it, but have not seen any specific data or claims on how low it lasts? I have had great luck with other Optimum products and ordered a bottle to start using, but wanted to be able to tell my customers what to expect. Any info would be much appreciated.

I've seen 2-3 months, not the best or worst IMO.

If you use OCW right after, I have seen 3 months
