So we are getting ready to paint our kitchen cabinets. The POs put formica or some other laminate covering on the cabinets. I started peeling that stuff off to mostly find nice maple cabinets underneath. The bad news is, at least two of the cabinets, naturally the highest profile cabinets by the window, have a layer of 1/4" particle board all over. Not a single sheet mind you, but a patchwork of pieces tacked in place by finish nails. Do I dig all the nails out and peel off the particle board hoping for a paintable surface under, or is there a way for me to fill in the series of gaps between the particle board and use a magical primer that will give me good results. (Good results being both pleasing to the eye and indistinguishable from the painted solid wood cabinets.) Thanks in advance!
