I posed the question of "what is polyurethane coated MDF" in General Woodworking, but it failed to generate.
A search on the internet for garage cabinets turns up quite a few hits for "polyurethane coated MDF".
Has any done this? Can you provide any details on what you did, and the results?
The MDF cabinets will be face-framed with solid wood (poplar).
I have HVLP. For some reason, I'm resisting the option to paint, maybe because it's too common.
