His video is excellent
I bought some 10 ounce "squeeze" bottles from the hobby store, the nozzle unscrews and the tip has a removable plug. I bought some Elmer's Wood Glue and did the 1:10 ratio with water he suggests. Shake shake shake, apply to a freshly cleaned bed, spread around with a brush, heat bed and it dries up nicely.
My prints are adhering really well and it's really nice to retire the glue stick!
