Sharon,
I guess that you mean, no gesso when used for pastels ?
When used for oil I would prefer a light painted ground of some kind. If it should be gesso or simply oil paint depends on the grade of absorbency you prefer.

Lisa,
The same stuff, just make sure it is MDF, not MDO. It is great stuff.
Actually, I left out a minor step, you do have to size it with rabbit skin glue, something you can cook on top of your stove. Ralph Mayer's book has the method.
That is right, NO GESSO for oils! The man is a wealth of information, I spent 2 1/2 hours with him on the phone,
You have to gesso for pastel because you need the grit.
Mr. Harding says it is one of the best and most stable supports around. Much better than any wood panel on the market and way better than canvas.
My cabinet maker suggest having it cradled in thicker widths of MDF, but you can use oak which is quite strong.
Allan, if you want want a lighter background, just use white paint over the glue.
Cheap, archival and easy.

Lisa,
After 2 1/2 hours on the phone with him, my head was buzzing, and I did not ask.
Two reasons I suspect.
1) The acid from the oils would not be able to react with the substrate
2)The oils would not be easily absorbed by the MDF so would not look dead and dry.

I am only using MDF panels now to paint on. A carpenter makes them for me with cradled backs, then I rough up the surface and apply three layers of gesso, sanding in between coats. Then I tone it and I'm good to go. I love these panels, no bouncing when I paint and such a silky surface to work on. Next I'll be gluing linen on them and I think I'll really love that surface to paint on.
I haven't tried painting on them without gesso, maybe I'll try that next. It just doesn't seem right.

This is great news for me! I have a source of free mdf panels of various sizes.
As long as rabbit skin glue does not involve boiling any rabbits I will give it a go and see how this support works for me.
I don't know what "cradling" means but I suspect there's a post about it somewhere on this forum.
Thanks for the info, Sharon!
