OK, after doing a search it looks like C2 Sandable Acrylic Primer is the way to go ...

Isn't the MDF already primed in white?

Nope, it is bare naked. Hubby bought sheets of it to build the mantle and bookcases.

Naked wood...! (((gasp)))
Sounds kind of "naughty" ;) !!
(oops...maybe I meant "knotty"...)

We're a C2 dealer (only one from Chicago to Denver!) and, yes, the C2 SAP is a good choice IF you're near a store. It IS "nicely low" on the VOC-scale of things.

(Like the NHL, we might be considered in the C2 "Norris" division...kinda meaning "up North" like the Minnesota Wilds' division)

* Regardless of primer choice, I'd wait a day b4 sanding. Many primers aren't really hardened-off enough to nicely sand the same day of application.
* Buy a top-quality primer! Cheapo's don't have enough dried thickness to sand. Solids content is often very low.

Knotty!!! Lol. Ok Will use the C2 (dealer around the corner) and we may paint with Cabinet Coat or maybe C2 Semi Gloss, depends on the learning curve I feel like at paining time. Thanks Faron for always answering my CC and C2 questions!

Depending where your store is, say Hi to Mr. Stebbe!!
He's at one of the Walls Alive stores I think...
One of the early C2 owners/partners.
* If you use S/G...be fussy when you sand the SAP primer...
* The higher the gloss, the more little flaws show up!
* You can lightly sand the first coat of either brand, but just wait a day in between!!
