I live in a warm, dry climate (So Calif).
I will be doing interior painting for baseboard and molding in one average-sized room.
In looking in my “painting cupboard”, I came across an unopened quart of exterior paint (Ameritone). I wrote on the can “1966” (!). Yes, I know my Q may seem a bit wacky but … the can is in good shape, the paint has been keep air-tight. Can I use this paint for interior undercoating in preparation of putting a water-based paint over it? Again, I fully realize my Q is “out in left field”. However, this paint is oil-based by a reputable paint company and I would be covering it with a 2010 water-based paint. The home is a quality-based home, the wood on which the paint goes is 90-year old quality oak wood.
If I’m foolish to even think of using a 44-year old paint, don’t hesitate to say so. The reason I am asking is I am assuming an oil paint is superior to a water-based primer, even if that is an
exterior primer. But I don’t know.
Last Q: Is Zinzer 1-2-3 as good a water-
based primer there is? (cost is no object). I ask this Q because I’m told it is the best primer there is.
(oil-based paints are OK to use in Calif from existing stocks but no new oil-based paint is being sold.) If the oil-based paint I have is not recommended by you for use, I’ll properly bring it to a disposable sight.
Sorry for being so long-winded but it was the best I could do.
