There's no green increments on the back Tom.
We had a new R/S on just for the Roughcast and it was a bit tight so machine would JAM.
In the end,we mixed up in gorilla tubs and poured it into the hopper which worked well.
Not an area I'm experienced in to be honest as never been asked for it till now.
I've a Ritmo m and gonna be pumping and then casting a Gable tomorrow.
I've a new 10 mil cap and new R/S but my water bottle has the red increments, not the green,but has the green lightweight float?.
