I'm building a cabinet that I hope replicates an antique piece I saw in a store. The inspiration piece is about 100 years old and has an aged, dried out finish on the exterior and was at a later date painted on the inside. The paint finish was crudely done and allows the color of the wood to show thru in places. As this is a new piece that I will apply varnish/tung oil to inside and out I wonder how soon after applying that finish I can paint over. Can I use latex, which I feel will give me a better washed look than an oil as well as the flat finish I desire. Thoughts?
