Definitely BIN. I was talked into getting another primer that can be tinted to use under the paint for my kitchen cupboards and am so mad because it scratches off. I did the upper cabinets with Zinsser BIN and I can scratch them all day and the paint stays. I will do the remaining with BIN even though it isn't tinted.

Yes Tinker.... You're one of the waaaayyyy too many victims of the "Realtor-induced" Paint-the-trim-and-sell-it phenomenon. I REALLLY WISH most sellers would leave well enough alone. Slapping-up a quick coat of paint usually causes MORE headaches for the new buyers. Sure....it looks good for a bit right before a sale, but then the reality of NO PREP sinks in! Latex paint IS RUBBERY for quite some time! That's the major advantage....flexibility. If it was as hard as Oils, it wouldn't breathe. The Truth/Remedy can be a b*tch....peel-off/sand-off/strip-off the existing paint. The existing paint not peeling now soon will be. And yes, obviously, choose Top-notch 100%-Acrylic paint in a Satin or higher sheen. Once the old oil paint is thoroughly scuff-sanded with 100-grit paper & all dust removed...you're at last ready for 2 coats of your new paint. Priming...wellllll....never hurts, but if you sand well, AND get real good paint, you're good-to-go! Faron

I agree with paintguy. Acrylics increase their adhesion with time. What scraps off after 2 hours may well be adhered after 2 days. As to Behr paints, I have personally made test samples of Behr Ultra, Marquee and WB Alkyd over sections of hard, slick, high gloss oil paint. I hand these to customers and defy them to scratch it off with their fingernails. They are wearing thin with literally hundreds of tries, but they are still intact! Wanting to see the worst case scenario, I did not sand or de-gloss the oil paint. I am an old school painter, raised on oil pains and somewhat of a doubting Thomas. I have become a believer. If someone's paint is "balling up", I would wonder what is on that surface? Was it cleaned of oils from hands or other pollutants?

Use a stripper(eco friendly types work ok) and remove all the old paint. Reason? If it peels now, it will peel later and take any new paint. Then clean the surfaces with soap and water and let dry completely(24-48 hours). Then use a shellac based primer(BIN for interior or BullsEye 123 for exterior, both made by Zinsser) and prime. Then use which ever paint you choose. The best paint jobs are 70% preparation, 25% paint, and 5% technique.
