Clear Gesso: Does it produce a translucent foundation layer? I was introduced to clear gesso the other day. I have always used white gesso, added pigment, and applied it to form the foundation layer. If I did the same thing with the clear gesso, will the foundation be more translucent layer of pigment? Will it start streaking?
I've used the clear gesso with pigments to create underpainting. Clear gesso mixed with acrylics can achieve a faux watercolor paint effect. (I found an example YouTube video here.) I personally did this a little differently. I mixed the clear gesso with the paint in a little cup and added a few drops of water. I dipped my brush in the paint and painted over dry gesso. (It had a similar effect, but I had more control.) 

To answer your question; It is definitely translucent upon drying and would make it more difficult (but not impossible) to achieve an even-toned background. If that is what you are going for, I would definitely stick to the white gesso. But, give the clear gesso a try. I highly suggest experimenting with it!
