Rabbit Skin Glue - do you need it?
I have some stretched but unprimed canvasses waiting to be sealed with Rabbit Skin Glue, but I am put off by the awful smell of it when you heat it. Do you need to use RSG? Or can you just use gesso, which I believe has RSG in it, or am I wrong. What is the longevity of canvasses just primed with gesso?
