2 problems with Glow. One it’s brittle, when dry it’s brittle, when wet it’s brittle. Be careful cause it will most likely break in the PTFE tubes.
Speaking of PTFE tubes, Glow is hard on them. Very hard. Glow is an abrasive. Not recommended in the AMS, but it will work. Wear on the PTFE tubes can lead to feed issues, also headaches. Ask me how I know.
Good idea to spend some time now and then to check those tubes, the outside ones and the inside ones. You should be able to tell if the walls have been worn down. The stuff is cheap. Check Bambus store for diameter etc. I can’t think of it off top of my head. PTFE is a consumable.
