I have lost it the last week...nothing has worked out. I wiped eight panels and these two were barely salvageable. Here is the question: What do you do to panels that have been painted on, paint dried and now you want to use it again? Do you re-gesso it? Do you paint over with a new oil ground? What? jb

I have just started gessoing over old acrylic paintings (my earliest work) of mine that I don't care for anymore. I'm painting in oil over 3 coats of gesso after I sand it. As far as oils - so far I haven't done this but people talk about "wipers" -- I guess they decide early if a painting is a stinker and they wipe all off (using a turpentine rag I guess) before it can dry. Now if it has already dried and it's oil -- I don't know the answer there for sure...
Hi Jeanne. You can paint a white ground over oil paint. Obviously acrylic gesso doesnt work here. Camille is right about wiping paintings that are not dry yet. On a dry panel, wipe off what you can, scrape with a palette knife any high points, and use oil ground (Gamblin makes a good one) and paint over. Let it dry a week or so.
(I've got a few panels waiting for this!!)
Jeanne, Maryanne is so right about oils. But on small panels, I just get a piece of sand paper and give it a good sand. The resulting finish is smooth and indistinct enough that I can paint over it without any further prep. When I use a oil ground, to me, it seems to leave a surface my brushes don't like.
