painting wood box

my buddy wishes for me to build him a box for his two tens....they are PIO tsw251r's   pretty universal sub....he is going to get probably some Comp Vr's later on in life...and the way it looks the specs for both subs match up very well....if anyone has some different information on the two subs please let me know.   Also if anyone knows the recommended port on the subs I would love to know that...but so far it looks like for a ported enclosure i would need about 1.25 cubic feet per sub...pretty easy but i want to get enough back pressure from the sub which just a little math shouldn't be bad....but ofcourse advice tips and calculations would be greatly appreciated. ha.   okay so onto my other bigf question.   How should i go about painting the MDF?  I don't want just a flat look on it , is there any way to get a glossy paint effect on the wood?  All I can think of is in primer and such which sounds right to me but i want the experts (you guys) to let me know!

Thanks for all the Help!!!

There are a couple of ways of getting the glossy look but here is one of my favorite:

Start with a High Build Sealing Primer. These usually come in two types, paint on and spray on. I recommend using a roller and paint on type for this project (spray on works best on tiny projects and crazy designs projects) Sand that with 400 grit sandpaper to make it perfectly smooth. Then spray a few layers of paint (at least 3). Let that fully cure. Sand that down with 600 grit sandpaper and get that perfectly smooth. Then spray a few layers of clear over that. Asssuming you are using a spray can, you'll want at least 4 layers. Now the fun part, wet sanding. Since you used the sealing primer, the water should not affect your box at this point. Lightly MIST the area you are sanding with water and use a wet/dry sandpaper 1200 grit to remove any "orange skins" Then buff and polish for that "always wet" look.
