That information is incorrect.
1. My methanol comes in plastic 55 gallon drums.
2. Methanol and PVC work just fine together.. Rating is "EXCELLENT"
Not sure what you are talking about.
I use methanol with PVC frequently.. never a problem or even a hint of one.. (I use Sch80 pvc.. the dark grey stuff)
The only thing you need to worry about when mixing methanol and lye in a plastic container is heat. The process of mixing the two creates lots of heat so if you have high titrating oil, you may want to mix only half of your lye at a time..
