MDF needs to be sealed.  Sanding sealant lacquer works well.  I usually use three or four coats - especially on the edges - light sanding or steel wool between coats.  Then sand, prime and paint using normal techniques.

Seal MDF, like all woods when painted the small hairs on it will stick up and they r a pain in the ass.  Use sanding sealer, fibreglass works too, you can bodyfiller it but that makes more work for you, depends on what sorta effect your looking for.  Id say ud b best off with the sanding sealer which u can get from like hardware stores.  If you join MDF to fibreglass and want to paint the whole thing, then somtimes ur better off doing a quick coat of glass ova the wood, so the shape flows alittle better

Sanding sealer is just a type of sealer that you can buy at the hardware for sealing wood. If you really aren't sure what your looking for just ask for help, yep I said it, ask for help, and if they know anything about their products they should be able to point you in the right direction. Good luck man.

Its a special sealer, thats usually used before stainning wood to stop the stain from going blotchy or absorbing too much, if you have ever tried to apply a wood stain to MDF you will see that it goes blotchy.  Most compnays that make wood finishes (Wattyl, Cabots, Feast Watson) make this product.  Sanding sealers make prep work on certian woods easier to do and it fills the gain to result in a smoother surface.  Simply brush on a few coats of the sealer and sand lightly inbetween coats, read the back of the can for the specific sanding info.  It helps when you try to paint MDF bcuz the paint dosnt get sucked into the board and the sealer once snaded makes a nice smooth finish.  I work in a paint shop so that sorta helps posted_image

Home Depot MDF cant be painted.  But the better quality stuff can.  There are about 3 basic types of MDF, the Home Depot kind, a light brown, fuzzy, about 20$a 4x8.  The kind that you can paint is a lighter shade, more of a plywood color, and is solid.  That stuff costs about 30 a 4x8 and the lightweight formula which is somehow extremely light and about 40$ a 4x8.  So it depends on the type.

If you are using the Home Depot MDFthen you're gonna have to listen to the others because you will never be able to sand her smooth.  If you can get your hands on the second level then its no problem.  Im not too sure where you could get it because we get it like 30 sheets at a time from a dist.  We use it mostly to trim houses.  Much easier to work with than actual wood, but looks just as good when painted.  We only sand the cut edges because the flat sides are already extremely smooth.  So if you can find it, it will definately save you a lot of time

i've had great sucess using a two part  primer called claw lock  it's made for refinishing furniture, ontop of that  use a high quality laquer based stain. https://www.cardomain.com/ride/805312/2  there are some pics of the finished product  the amp racks are covered with that paint  the amp rack cover still need a second coat of it.
