Well, did some research on Windshield Washer fluid and Meth.
Here is what I found:
-25 degree 'blue' Windshield Washer Fluid from South/Win, LTD is ~40% meth. So many places sell that (Walmart being one of them) but, I needed to find a place I could order and get it from.
In comes Napa. If I get this version:
https://www.napaonline.com/en/p/WWTMINUS25
I'm getting a good amount of meth included.
This is the data sheet and how I found the info:

This shows the ~ratio -- you'll see its ~40% meth even though its a 'trade secret' noted in the above doc (look for South/Win and -25 in the image below -- that is the make-up):
Can't find the Pitt-Penn -- that is the one to get if you can! ~45%!
Anyway, the NAPA brand is 2.99 per gallon for 40% meth -- not bad and is a great start. Anything lower than -25 and I've found they add glycol to it -- not what we want.
I really want to be closer to 50% - So, I started looking at HEET (in the yellow bottle):
This is 100% meth in 12 oz form. I found it for 1.77 on Amazon:
https://www.amazon.com/28201-Gas-Lin.../dp/B0016GXNC4
Now if I bought 26 of those vs the 24 pack, I save .07 cents YET I get 24 oz (2 bottles) more -- go figure ;o)
So, if I use 104 oz of WWF and 2 bottles (24 oz) of HEET, I'll have almost 55% meth!
So that would make it $6.53 per gallon -- and that's not bad for ~55% meth!
I could remove a quart of WWF and use 32 oz of HEET and I'd get closer to 60%
I think this is a cheaper way to go vs buying the pre-made mix. Now, I'm hoping to find meth in 5 gallon pails here -- that would make it even cheaper for sure, but this is not bad and its a bit more available...
