[TheForge] Gummy plastic coating for augers, etc.?

[Jay]

If the part is sealed or nonporous, a PVA coating may work. There are 
strip-able coatings used in commercial painting operations. I use to use 
a strip-able booth coating on my spray booth and have used a similar 
coating for sign painting. They both remind me of the PVA release 
coating that we used on fiberglass molds. Think of watered down Elmers 
white glue...
