    I'm going to hopefully modify my 3pi theater series speakers to include 2 12" woofers, and since my speakers are just bare MDF right now, I might as well finish them to make them look at least a bit respectable.

    I want them to be able to play outdoors (not in the rain or anything) if needed, so I figure veneer or other paints might not be a good choice.

    We finished one of my friend's subwoofers with the spray can truckbed liner and it looks ok, but not spectacular.

    Im wondering which brand you guys would reccomend? Also, what sanding techniques do you do after you have sprayed a few coats of it on?

    Finally, what kind of primer do you use on the bare MDF first? Ive got some generic wood primer in the garage and was wondering if it would work.

    Thanks!

    I'm an ex-painter and now bodyshop manager, There are several automotive primers that would work very well and are probably a better bet and more durable than any woodworking product out there. Use a good two-part primer with a high solids content.
    There are also some very high quality sprayable bedliners, but for the best finish, the application should be done by a pro-(if you can swing the extra bucks). There are too many variables(gun setup/temperature/humidity, as well as the aftermarket product that you are using) to allow for a quality finish. But it can be done.
    I would suggest taking your box to a quality bedliner shop and ask them if they could shoot it, (and, of course what the cost is) with some leftovers(there is always extra product when you paint something, that will just get disposed of) If they're a fair shop, and if it's already prepped out, the cost will be minimal

    good luck

    Jerry.
    I use this stuff all the time as a fact just finished another sub cabinet today with it.
    I use Dupli-colour out of Wal-Mart cost $8.00 tin.

    The tricks.
    Speaker cabinet pre and more prep to get a 100% finish.
    Never mind fancy primers.
    Just fill all the spots that need filling with wood filler.
    Then prime with ANY cheap black FLAT paint.I to use the Wal-Mart House paint nothing more than the cheapest for me.
    Appy 2 coats of this.The first if you need more filler in spots do it now.
    Then prime again to get a even cover of the Black.

    Open your can of liner spray.
    Spray in a vented area this stuff is hard to breath in a small area.
    Stand back a foot and spray a even coat over your primer.
    Nothin to it and if you try a few small pieces you will get the knack.
    And will even have some left out of the can.

    Thanks for the opinions guys!

    AllanRW, I think I will try your idea. Do you sand the truckbed liner after it has been applied and dried?

    One more tip- don't spray it outside if it's too hot or the sun is shining where you will be spraying. I've done this and the stuff dries before it hits the box (in the air). You then are left with a black "dusty" uneven box.

    Alan, that spray comes out nice... you've inspired me to redo my livingroom sub. I'd already painted it satin black and the paint ran a little in some spots and has brush strokes in it.

    Perhaps if I use the Dupli-color it'll be respectable enough to come out from behind the CD rack where it is now. [​IMG]

    Thanks.
    Give it shot on a sample piece of wood first.
    Like I said prime in a black finish first.
    Then all the liner spray is for is just texture.

    Allan, do you use the cheap .99 interior/exterior spray paint at wal-mart as your primer, or do you use there regular primer, then the liner spray?

    This is what I said before.
    Just use any flat black paint.Nothing fancy.I just use the Wal-Mart brand as it is so far the cheapest black paint I can find.

    No the Black paint is the prime coat as well as the under coat.
    I use 2 coats to give the clean black top coat and then a thin spray of the liner spray.
    No primer just the black.
    I may refer to the black as primer sorry just that is my prime coat then top coat.
    All out of the same can.
    The latex paint will dry in a few minutes and spray on the liner coat and paint from start to finish is done in about 1hr time.Depending on the temp in the area you are finishing.

    AllanRW that paint work looks great, I was thinking of going veneer but after seeing yours I might give that a try.

    Thanks for the idea. I picked up a can today at Walmart for $6.95 in Southern Cali. I'm just glued all the panels of my DIY Sub today. It needs some sanding then the painting will begin.
