Question about using a water-based finish over oil stain

For years, I was told you could not put a water-based polyurethane over an oil-based stain without a mess. My old boss in Grand Rapids swore by using an oil-based topcoat every single time, saying the water-based stuff would not stick right and would look milky. I finally tried it on a small maple cabinet door last month, after the stain had dried for a full 72 hours. I used a light coat of General Finishes water-based poly, and it went on perfectly clear with no issues at all. The finish is hard, clear, and has held up just fine. It saved me a ton of cleanup time and smell. I guess the old rule was based on older products that weren't as good. Has anyone else switched over and found the same thing, or did I just get lucky?

Oh man, this is such a common debate! I read a whole article a while back that said the same thing, that modern water-based finishes are way more compatible now than they were like 20 years ago. It said the key is just letting that oil stain cure completely, not just dry to the touch. Your 72-hour wait probably made all the difference. I've been too scared to try it myself, but your test makes me want to give it a shot on my next project.

Actually the cure time is more like a full week, not just 72 hours. But waiting longer definitely helps a ton.
