Does anyone know if you can prime a substrate for Dye-Sublimation with GESSO?

I know that the coating used to prime glass and the like for dye-sub heat pressing is polyester, which is a synthetic polymer. Gesso is also a polymer. I was wondering if any of you have tried using gesso to sublimate a photo onto canvas or anything else. I want something cheaper and more profitable to prime substrates other than the super expensive primer LaserRepro sells to coat tiles. From my understanding, the only reason you can't sub on natural fibers is that the heat won't open any pores in the fibers like it will with a soft polymer. Any suggestions?

thanks,

Isn't Gesso Acrylic (plastic) based?
Hope yer press isn't too hot...
I'm envisioning quite a gooey mess...

I'm also envisioning a void warrenty in print durability.

We press FRP (fiberglass-reinforced plastic) for a number of things and have had no problems. I'm not sure if the fiberglass is what keeps it from melting or just the gauge of plastic used. We also press really thin adhesive vinyl sometimes. It only takes about 40 - 50 seconds to sublimate at 400 degrees. I wonder if maybe the gesso would hold up if pressed less than a minute. What do you think? Thanks for the reply.
