Panel help?

[Sharon Knettell]

Why do you care if it is lightfast IF you are going to cover it with paint? And you are actually sealing it with rabbit-skin glue?

If you want a stained or translucent look you could just cover it with lead white and THEN put a wash over it.

At the time I asked the question I wanted to know if I could use the light brown color as a base. THat's how lightfastness came up. MDF seems more structurally stable than hardboard, except for the DPI I mentioned, so eliminating the gesso and covering it with paint should work. I have something I prefer much more, copper.
