Bodhi we were warned about the dangers of MEK when I was in the Army working on aircraft.. In fact I think anything containing it was banned but I'm not sure if I remember that correctly.
I'm kind of shocked because I'm seeing other videos where they are working with the same substance, it's Highly Cacinogenic , no gloves, no mask no protection.
and looking up Polyfiber they absolutely list it on their page, I'm sure it's on the container.
Wild they aren't using protection. I'm guessing it's just slipped by.
and as a side note:
Rotec is still making Radial engines so that's always a possibility if you don't want to custom build a VW one.
I thought that was pretty sweet too.
