I haven't had much a problem using the glue for longer dyes..... the glue gets a little mushy.... but still seems to stick enough.
Well, I'll find out soon enough I guess. It's just that I was planning on using the same coat of glue for a series of dyes (for different shades) that will involve a fair amount of cutting on the disc between dips. That cutting is going to be a pain if I have to worry about not touching the glue the whole time.
