Difference
MDF-Medium Density Fibreboard-Compressed paper like substance-used as a substrait for veneer-sort of took the place of particle board as a substrate. Can be, but I've never used it for base for laminate. Interior and Exterior Trim-many profiles are made of MDF and primed for your enjoyment. Paints up real nice. Used to pucker when nailed-not so much anymore. Edge nailing separates it-not good.
MDO-Medium Density Overlay- Plywood that has either one or both sides layered with a paper like veneer. Paints up nice. Good for exterior panels-signs-stuff like that.
I use it for the panels / shelves / flat buildups of shelving units. Needs edge or edgeband to cover plys. Good stuff-2 sided is a bit more stable out of the gate-the one good sided sheets tend to come bent in one direction, rather than the almost flat of two sided.
I used MDO for a pontoon boat deck 20 years ago and it is still doing fine except where I made a penetration that wasn't properly edge sealed (shame on me) I am convinced it is pretty good stuff.
This is a boat, in salt water that gets used 12 months a year with more neglect than maintenance.
