yes but you cannot put latex on top of oil based surfaces You actually are NOT advised to put oil over latex surfaces, which is why you're supposed to prime will an oil-based (alkyd) primer. Latex and Polyurethane should always have a layer of oil-base beneath it.
oil based
No, oil paints will always dry slower than water based paints.
Oil paint ? are you refering to an "oil-based" paint or artist's oil's? you can add "japan drier" to both, and it only takes a little bit .usally "unfininished plywood would "suck up" paint,as quick as you applied it.Remember you have to stir it up real good.
Only if the urethane paint is not waterbased... Urethane Paint cannot be mixed with anything except other Urethane products. Urethane Paints do not work on the same principals as "oil based" paints. Oil Based Paints rely on evaporation to dry. Urethane cures. by chemical reaction.
If water based only boiling water will soften it if oil based not worth the trouble.
Paint it in an oil based paint and dry it totally before getting rain on it.
Alkyd paint has a resin in it to help the oil in the paint dry faster, oil based paint in my opinion has a more vibrant colors, both in depth an brightness, waterbased seems to be toned down some-what. Wood paint can be either water based or oil based and even water soluble oil based. Oil based alkyd paint lately are used for things or areas that might receive abuse, and because of the slower drying time the oil based alkyd paint will show less brush marks then water based paint.
Pressure washing is the best option.

oil based
Yes. Clean and degloss the oil based paint, apply an oil based primer, then apply the water based paint.

Yes, but be sure the kilz is completely dry before applying the paint. The Kilz formula is such that it has no effect on the application of water borne paint, when it is completely dry.
Use Acrylic paint, oil-bases paint takes longer to dry and isn't made to withstand the elements.
