no----but oil base primer needs oil base paint and water base primer you can use oil or water base over it----doesn't matter whether it flat, matte, semigloss, gloss, high gloss on top.
no you don't. Just make sure you don't paint latex over oil.
Awesome. Thank you!
nope! any finish will do
Kelly: Lynn gave you perfect info!! Thumbs up!
Make sure to thoroughly clean & dry the wood first! No paint will adhere to " greasy ". A water based flat latex paint would be a good base coat then you can apply a 2nd coat using any water based paint be it another layer of flat, or satin or semi gloss. Good luck :)
