If your referring to the section on glue Tim Baker wrote yes I quess.First pour etc.I use Fredrix canvas sizing.It comes out amberish brown and it works for me.Some people like knox gelatin.I guess the lighter the color the stronger.Over heating it is a no no and turns it darker and weaker they say.I keep it at about 115 degree F.Never over 120 F.It'll curl your sinew very quick.
