The grittiness Is likely due to raised grain which will happen regardless of primer use; more so with water based.

Wasn’t aware that MDF had ‘grain’ :)

I’ve never had any problem painting MDF or any issues with routed edges, but I have never used anything other than oil based enamel. Spray primer will leave a slightly rough/dusty feeling surface – it’s just the nature of the beast, and it needs to be knocked down before applying a finish coat. I just spray multiple coats of the finish paint as I’ve never felt that primer does anything that regular paint wouldn’t do anyway, and don’t see a need to purchase two products when one works just as well. Don’t have many pictures, but here is a bandsaw base made with MDF and IIRC three coats of enamel… as you can see, it’s almost a mirror finish:

If you want to see some truly impressive stuff made from MDF, check out this thread over at OWWM, where most of those faux bases are made from MDF:

shopmade machine bases: the cream of the crop

Not exactly shelves, but still darn impressive, and shows the wide range of finishes you can get with the stuff.
