Not to beat a dead horse but, some more suggestions.......
Are you using spray cans? If so are you mixing the paint well? Shake the can well and make that ball rattle.
Are you putting on too heavy of a coat? Use thin coats and sand with very fine grit paper between coats. Letting each coat dry well and use 400-600 grit or even heavy brown paper bag to knock off the sheen between coats.
I'm not sure about humidity in Nova Scotia but, if you could use a light bulb (lamp) or an electric space heater (DO NOT USE A FLAME OR MICROWAVE OVEN) near the item while drying may help.
Are you using an oil on the items before spraying? Some oils never dry completely (lemon oil and mineral oil come to mind) if so try using boiled linseed oil and let it dry for a few hours or a day, it will dry and fill pores too. Lemon and mineral finish on the items look good and really pop the grain but they must be wiped off very well before finishing. (or, don't put any more finish on them at all)
Last but not least, try a coat of paste wax and buff to a sheen after the finish has dried. Depending on the cutting, I think this looks the best anyway.
Maybe something here will help.
