Assuming the 50 is VG, the 40 is PG and the 10 is DW, that would be some mighty thin
juice. I imagine you would need some hellacious wicking to keep that from leaking which is why I never tried it.
I agree though, that adding DW makes the PG and VG compounds more resistant to thermal degradation.
That was my hypothesis back in January and was
subsequently tested by ECF's very own Mikepetro in April. My hypothesis seemed to have been proven in his testing. Just out of curiosity I wouldn't mind seeing the Italian report. Also when was this study conducted? It would be TOO funny if they got the idea from Mike and I and the above linked posts.
