Proportions, please?

Mostly MEK. I added a little Xylol (AKA Xylene) because
I thought I saw it listed in an MSDS for coil dope. However,
the MSDS for the General Cement product lists only MEK
although the thinner is Toluene. If I do it again I will use
straight MEK. I added the styrofoam until the stuff got to
what seems to be the right consistency, about like honey.

A word of caution to anyone considering this: when starting this
procedure, fill the container only a third of the way with MEK. All
that polystyrene needed to thicken it up to honey-like consistency will
increase the volume a lot.

I have a half-pint mason jar that started with a third of MEK. I fed it
one and a half letter-sized inch-thick slabs of foam and it's still not
done.
