I know that generally speaking, you’re not supposed to paint oil paint over latex paint. But what if you’re talking primer? I tried covering sharpie marker stains on a door with latex kilz and three coats later its still showing through. I’d like to try covering with some tougher oil based kilz. Will it peel like the paint tends to or can you use oil based primer over latex primer?

First of all you absolutely CAN use Oil Paint over Acrylic Paint… it seems that many people have received the opposite info from sources that appear professional, but in reality are actually amateurish…so now why didn’t you simply use a little Lacquer Thinner on a soft rag to remove the sharpie marker stains at the beginning? this would have been the best thing to do…
So now yes, you can use an Oil Base Stain Sealer over those marks without incident, just use a good name brand like Kilz and use an Exterior Grade version…

That’s weird that it’s a myth, seems to be believed by every place I looked online, they even put pictures of the paint peeling off and claim that was why. I started to clean it off but its basically the whole door and there is also a bunch of ink stamps that were not coming off all the way, so I *thought* it would be easier to just cover it with primer. 3 coats and it still bleeding through however has me ready to just sand the whole door and start over! Thanks for the info.

Mr. Dave is correct.  Oil based primer can be used over acrylic (Latex) paint without causing peeling.  If peeling happens it is because of the solvent used in the “primer”, some spray cans of primer or paint can use Xylene as the solvent and this could cause problems over cheap paint. Same holds true for lacquers.
I use oil based primers all the time, inside and out, over standard latex paints and never had peeling.  Don’t know what the other sites are talking about, possible they are quoting an original source that got it wrong. 
The truth is; Never use Latex paint over Oil based paint, the latex will have problems sticking to hard oil based enamel.  This applies to finish paint not primer.
Try a spray can of BIN primer over the marker stains.  This is a shellac and works well, might take 2 coats.

Thank you very much! I’ve got a can of Kilz original interior/exterior from painting my exterior door a few weeks back so I was going to use that if the “rule” only applied to paint and not primer. You saved me a ton of work I am sure! I never paint over paint without thoroughly cleaning/deglossing and priming.?
