all i have to say is dont forget the primer. any kind of porus material be it wood or drywall or anything like that will suck paint up in a hurry so it can be helpfull to prime it first. i think the clear coat should be ok on it. i think it depends on what kind of paint your useing.

With MDF/Particle board, you're definately going to want to primer it. Sand it smooth first, then hit it with a few coats of primer( I think you'll want latex based, not quite sure). Sand that, if there's any bare spots, go for a few more coats of primer. Sand again. Then lay down the color, wet sand it if you want a glossy finish. If it's going to get a lot of wear, you can then go for a clear coat. You should be waiting 10-15 minutes between each coat, and either bake it or wait a day between sandings.

If you want the ultra glossy look you'll need more then primer. For the super glossy look apply a thin coat of bondo over the mdf, once dry sand smooth. Then use the primer, (3-4 coats) wet sand it smooth(600-1000), Apply color (4-5 coats) Wet sand every 2 coats (1000-1500), wet sand final color coat (1500-2000). Then Clear coat (light use 3-5 coats, Hevy use 5-7 coats) Wet sand every 2 coats (2000-2000+). For really crazy smooth look wet sand the final coat then hand glaze. Remember black is one of the hardest colors to get super smooth and glossy, as it shows any imperfection or unevenness in the material below...So take extra care to prep correctly.

Hardly you should aim for the best effect and quility you can get and that is the way you will get it by doing things the long way and not taking to many short cuts.

I like the Rustolem brand . But any Rattle can should do fine, so long as the primer ,color and clear are the same type (Laquers with Laquers, Enamels with Enamels.....Then Brands don't matter!)

If it's just the inside of the box and your not going for th super shiney look. A good sanding, then A couple coats of primer followed by 3-4 coats of color and 3-4 Clear should be fine. big thing with MDF or particle board is to seal out moisture, as it will cause the wood to crumble over time.

Good luck, and post some pics too!

No matter where your box is you allways have to worry about moisture, it's in the air all the time, even in doors.

For painting, the inside a speaker box, I'd sand the primer with 600Grit (after all the coats), then sand the color with 1000 -1500 Grit (1500 can be hard to find some places) before the clear. Then just lay the clear on and don't worry about sanding it (as no one should see it, and if they do the light will be so low that the clear's shine will be wnough to look smooth.


Good Luck!
