Can you apply water based polyurethane over tung oil?

Yes u could put a acrylic poly over tung oils, make sure your tung oil is dry my take2 months.oil urethanes yellow in time acrylics will but last twice as long before they yellow.if tung oils or stains oli base have just been done them no u would not want to put on acrylic. Needs at least 8 weeks to dry.
