I have found that using a black primer is beneficial and then sand the primer back with 200 grit just enough to remove the brush strokes (if you have them) because they will show through.
It is still very important to have all of the glue joints on the MDF prepared well, otherwise they will still show up

Ok, here's what I've learned.
Prep your cab like you are going to do a piano fiinish. Don't count on the truck bed liner filling in any defects.
Use flat black paint for the primer. I used a mini (trim) roller with good effect. Multiple coats is better. Thin the paint just a bit, not too much. Sand between coats. Keep thinking about that piano finish.
The paint will tend to pool at the edges, which you must prevent.
It's not easy to get an even finish with spray on truck bed liner. Spray from about 2 - 3 feet. Use even strokes, start and stop the spray 'off the wood.' If you spray too much, the liner will pool and get shiny. Shiny is bad. Keep the angle and distance of the spray constant.
Al Wooley (RAW Acoustics) is a big fan of spray on truck liner (and gets very good results), but next project I'll prob try the roll on type.
HTH.

More tips.
The nozzle tends to get get clogged. Keep it cleared. Big drops will dribble down from the nozzle, so watch where you are walking.
Use an area with good ventilation! When I used my living room, we had to spend the night in the cellar until the upstairs cleared out.
Here is how my twin Tumults looked at the NorthWest Washington DIY meet. They need one or two more coats of liner, and a bit of touch up in the woofer recess.

Yes I have used it a little.
Ok NO big deal.
Fill all the edges and holes, sand smooth.
Paint with any roller.
I use cheap 3" rollers at the $1.00 store prime it with any cheap black paint.
I use Latex from WAL-Mart .
Dries fast and needs only 2 coats.
I can complete a sub finish from start to finished in 2hrs with spraying on the liner spray.
All this time really is dry time not hands on time.
As Thurman said to stand back about 2-3feet as the over spray is what you really have to control.
as well as the splatter from the thickness of the product.
Good luck

From Wal-Mart.
$7.50 CND per spray tin.
1 tin can do 4-5 sub cabinets.
Once you get the pre work down.
