A couple months ago I bought some Elvamide off an eBay seller, who I've purchased items before and seems to be honorable.
Today I thought I'd try to make some solution, and after developing a stir motor, I heated the Methanol to just under it's reflux point per the Dupont instructions and processed the mix for nearly 2 hours without the Elvamide really showing any signs of dissolve.
Have anyone else tried this stuff?

6 hours of mixing and the Elvamide in Methanol is barely dissolving. I'd steer clear of the stuff on eBay. I've set it at just below the threshold of the boiling point of Methanol. I can tell some of the pellets have started to dissolve only because the fluid is turning opaque. The Grolsch beer is currently the only thing keeping my patience!

How concentrated did you try to make? How aggressive was your mixing? Pulverizing the cubes before adding to methanol should help speed up dissolution.
Oh, and be careful! Methanol is pretty toxic and the vapor is very ignitable (I did not see any condenser on your flask).

Oh yeah, did that earlier and a bottle of The Kraken...we're good-to-go...maybe I should see if the Kraken has the right properties for a Mylar treatment!
