I need a hardener for UPOL 745

I have a barely tapped gallon (3L tin) of UPOL 745 Gold Lightweight Filler but it's been about a year since I used it.
The filler stirs up nice and creamy.
The problem is the hardener, it has separated into a blue gel and a clear liquid like water. Try as I might I cannot get it homogenized back together.
A test spread shows it does work but leaves tiny blue "curds" in the filler,,, not good.
My supplier doesn't sell the hardener separately. I found UPOL UPO 724 hardener online and I'm curious if it's compatible with the 745.

Did I read on the forum that hardeners from different manufacturers can be "crossed" in desperation?
I'm kinda' leery of crossing manufacturers products.
With the difficulty of getting some supplies these days I'd hate to lose this filler just because of the hardener.

I do have an email into UPOL and am waiting on a reply.

Thanks, K. Lee
 
Well,, I received my replacement hardener,
BUT.
The thread's about dates on products have me concerned. If I'm reading this right it's from 2019. Here's what I have.

That's not the manufacture date code. It's located on the bottom of the tube on the seam. The 1st digit is the year. The 2nd and third digit is the month.

As an example, 1056853 means it was manufactured in 2021 (1) and (05) May.
This example would be good until May of 2022.

See this thread for a pictorial example.

WARNING......product failure

Life is a learning lesson, so is painting a vehicle. As some of you know I had a filler issue not drying. Being the amateur, I thought it was my mistake by not adding enough hardener ( I know I added enough ). Well today I was still stewing over it so I called Evercoat and explained the...

After closer inspection of the crimp on the tube I see the numbers embossed in the crimp.
(Thanks MJM)
Again,, if I'm reading it properly it is indeed out of the year window if applicable to this particular manufacturer.
Numbers in the crimp - 0038010
Year: 2020, Month: March, making it a year and five months old.

Dare I risk it?

Only you can make that call. I'd use it if the hardener looks good. It's not like it's 2, 3, or 10 years out of date.
