If it's an old painting that you've dusted off to rework, how can you tell if you painted it with oils or acrylics? That's the question Papaya is asking on the forum:
Oil Painting FAQ:
• Using Oils Over Acrylics
• Why Has My Oil Painting Cracked?
"So often I want to rework an older painting only to forget what medium I used, especially since I paint with both oils and acrylics. Is there a way to tell if it's either one without knowing what was used? If there is, I'd love to know. From now on, I'm going to label the back of the painting as to what medium I used especially since you can't paint acrylics over oils.If you know of a way to tell for sure, share it on the forum... or leave a comment below.

Maybe you could just use oil regardless of what you used before. Oil over acrylic should be safer than acrylic over oil.
