Latex and Oil

I have recently bought a house and noticed the trim peeling. The previous owner has painted latex on oil based paint. What primer can use to seal this problem so I can go back w/ a latex paint on the trim.

Best to scrape and sand any loosely adhering paint
Then prime with a quality oil-based primer
Then top coat with a quality latex paint

Although latex paint directly over oil based paint is likely to fail, latex paint over oil-based primer is fine, and would be the procedure the prev. owner should have used

Thanks for the help, I just wanted to make sure i can paint latex on oil based primer. I looks like all my trim in oil based paint. Is Kilz or Zinsser 123 best.

"Original Kilz", the oil-based Kilz (the others are latex) is a decent product and would work
But it's really for stain blocking, rather than adhesion
Zinsser's "1-2-3" is a water-based primer and would not be appropriate
Zinsser's "Cover Stain" is oil-based and would work fine
It is also designed to block well, but has more adhesion than "Original Kilz"

As blocking is not needed, if I had my druthers, I'd use Ben Moore's alkyd (oil) "Fresh Start" or the Sherwin Williams equivalent off-hand, but if the OK or CS were available I'd use them

Is the peeling paint very fine that rubs off with your hand? Or is it cracked thick peeling that you need a scraper to loosen. The real problem is oil paint over latex paint...this is the worst kind of fail. Either way you need to sand, scape or strip off all this loose paint. Sherwin Williams does have a latex "bonding" primer. Or the wall and wood alkyd primer they have. This does need overnight to dry.
