Thank you, George for that clarification. I was concerned by the warning in the “Quick Reference: Choosing Your Ground” decision tree where it says to avoid alkyd primers under the “Oil Paint on Rigid Panel” section. I was very happy to learn that I can continue to use it on my panels.

If alkyd primers are no longer recommended as grounds for oil paints (see George’s recent article “What Happens When Your Paint Ground Cracks), does this also mean alkyd paints should be avoided for underpaintings? If we choose to continue using them, should a bit of alkyd medium be added in succeeding layers?
