I have a pantry that I'm fixing up. Part of the door frame wasn't painted in a gloss like the rest of it. I have sanded the frame (leaving the properly done part). Due to it only being a small area, I'm hoping to save money and not buy a new prep coat. Previous owners have left a tin of frame high gloss enamel. Is it possible to use this Prep 4 in 1 water based paint, that I used for the pantry walls. And then use the oil enamel as the topcoat?
Or will that just not work at all? It doesn't have to be the ultimate solution, just something that can save me money and fix the situation for now I think.
The last photo shows where I need to paint.
