    My Tempest sonosub is coming along nicely, and I'm looking forward to finishing it in the coming week.. I want to finish it in black, and would like the end caps to be glossy black. I've seen several people have this result, and just wanted to know how it's done. Also, is it possible to veneer over a rounded or bullnosed endcap (considering it's a round cap obviously)

    thanks

    That like pretty much tells you exactly how to do it. It is a very hard and time consuming finish but worth it once completed.

    Ok that is way too much work for my application [​IMG] after all, this is just a sub.. not a masterpiece .. hmm... well anyway, is there a simpler way.. perhaps not piano finish glossy, but just a nice looking finish. a veneer perhaps?

    You can get a high gloss finish from MDF very easily. Spray the bare wood with clear coat from a spray can. 2 or 3 good coats. This seals the wood and prevents the paint from soaking in.

    Then paint it whatever color you want. Then apply 2 more coats of clearcoat and you will have a beautiful high gloss finish.

    Another option that looks very nice would cover the beast in veneer then apply black stain. Then apply a couple of coats of high gloss varathane. This is the nicer option in my opinion.

    Another easy option would be just get some laminate. They have lots of colors and sheens available. Just glue and trim.

    If you have any fiberglass repair shops in your area see if you can get one to jel-coat it for you.Ive worked with fiberglass for several years and jel-coat is pretty inexpensive,very durable,can be made in several colors,and can be polished to a mirror finish if you wonted to.
    Another thing good about it is it is a sprayed on product so any shape of enclouser would be possable to do with no problems. Good luck[​IMG]

    As Rob said, gloss black Formica laminate is probably the easiest way to get your desired finish.

    I have had good luck in the past applying flat black paint (over a primer coat) with a few coats of clear Minwax polyurethane over the top of it.

    I just finished my speaker stands last week. I copied the stands that Brian Steeves made. I used maple veneer for the side panels. For the other surfaces I sprayed the MDF with a cheap black spray ($.99/can) then used a Rustoleum Lacquer spray over that. Several coats (4) of both paint and lacquer. I sanded the second paint coat w/320. It worked out really well and not too difficult or expensive.

    I've had excellent results with the following procedure:

    Sand the surface smooth (220-ish)

    Spray a couple of coats of lacquer primer/surfacer

    Wait a few days (this is important)

    Dry sand with 400g -but don't cut through the primer

    Spray a couple of coats of automotive lacquer

    Lightly sand with 1200g

    Polish with automotive polishing compound

    Finish with Meguiars #7 glaze

    This process gives a dazzling mirror finish. The "secret" if there is one is the primer/surfacer. It's a high-solids, high-film-thickness material that sands beautifully. It's available at automotive paint stores. Make sure you let it dry completely because it shrinks as the solvents evaporate out. You want to sand after it's completely shrunk.
