Any reason why MDO ply can’t or shouldn’t be used for exterior applications such as soffits? Often I’ll see some type of plywood (or, more commonly, vinyl) being used, but the grain always shows through the paint, and I hate the look of vinyl.
MDO is supposed to be weather-resistant, right?

I use a lot of MDO ,3/8" to 1 1/8" thick .I like to order it primed .
I order it usually from a supplier in Maryland ,Harbor Sales .
They also have a cutting service .E mail them a derwing and they can cut just about anything on a cnc router table . Pricing is good and they deliver about 3 time a week to my area ,Northeast New Jersey.
Absolutely. (In reply to can MDO be used outside). That's why it's often called "signboard" and is often used by state highway depts. for road signs. Great stuff--takes paint well. As I said in some other thread, we used it to replace a soffit and wide (16") fascia that had been put together out of "exterior grade drywall" that had turned to mush. The MDO worked very well.
I used it for soffits on my new home, built in 1999 in New York. Due to an unplanned job change, had to sell it last fall. But, it looked good as new so far. I used ½" thick MDO, good (i.e. faced) one side. Primed and painted up real nice. Stylistically, it looked so much better than any vinyl or unfaced wood.
For the facia I used Hardie Facia.
