BACKGROUND INFO:
Interior walls were painted with an oil based paint many years ago (maybe 30 years ago). Paint is still in good condition, no chalking or peeling.
Oil based top coat paint is pretty much going the way of the dodo bird so planning to switch to water based acrylic paint for the new top coat (same color).
I know that latex paint can be painted on top of oil based primer since I've done that before. I have a gallon of oil based primer so I plan to use that until it is used up, for the interface between the old oil based paint and the new acrylic top coat.
QUESTION:
However, when that gallon of oil based primer is used up, would it be better to buy a water based bonding primer or more oil based primer? IOW, would an oil based primer be more guaranteed to stick to the old oil based paint better than a water based bonding primer? (Water based bonding primer would be easier to clean the brushes and rollers)
