I would definitely go with ConMah's answer because all the paint has to be removed to get rid of all the steel wool residue , Especially when using a latex paint which is water based , Any steel wool residue left behind will oxidize from the water content in the latex paint after the paint is applied which will bleed through , After sanding to bare wood , Apply Kilz or Bullseye primer first for the paint to adhere better and cover up any dark spots , If you need to scuff the surface between coats , Use sandpaper , Never use steel wool , Good luck
If you don't address the causal problem of steel wool residue in the paint it will continue to oxidize and corrupt the paint and you will be back in the same position again. If you are going to do the job do it right the first time. Sand it down to bare wood and repaint the window trim without using steel wool. That way you won't have to come back and re-lick that calf.
