I have had less than desirable results using Sherwin Williams Multi-Purpose Oil Primer to prime previously varnished kitchen cabinets. For what I wanted, this seemed to be the best choice at SWP. The primer went on bad (kinda sticky), did not level at all and even worse did not sand well. The primer made plenty of dust but seemed to take a great deal of time and effort to bring smooth. I used to use Dutch Standard Alkyd Enamel Undercoater (showing my age) and it was so nice to work with and always left a super smooth surface with minimal sanding. I try to avoid the alkyds but never seemed to get the results I want with latex primers on cabinet work. Of course I am old school and I am brushing and roll/back brushing these surfaces. I plan to finish with Pro-Classic Latex which I have had satisfactory results with in the past on trim work. Anyone know of a good enamel undercoater please let me know. Thanks!
