Best material to paint glossy black piano?

ARIYAHOOR · 27th December 2011, 02:00 PM

Hi there dudes
A friend of mine wants me to build him a huge horn-loaded 3-ways speaker... he want the finish "Glossy Black Piano" ... I've painted black piano before on plywood but he want something exactly like pianos ... I just want your opinion about the material? what is the best material to paint in Glossy black? (bare MDF, Plywood, Chipboard with veneer, etc...)
like this:

I'll do:

1- use cellulose undercoat
2- wet sanding with Makita and then with some handy power
3- spray Black paint
4- wet sandpaper the black in different grades (1000 > 1600 > 2000)
5- spray semi Polyester
6- sandpaper and polish it again
7-after a month or so I'll wax it

shed some light if I'm wrong

Core material of your choice and HDF shell (3mm thick). Below picture shows cross section of a budget speaker made by professional carpenter. Veneer-HDF-MDF(green, water resistant)-HDF.

A fine tight grained wood veneer like poplar, birch or maple. Core material of your
choice.

I'd use MDF for the base material. I think your technique is just fine and the results look good.

Plastic laminate works well as a top, too.

4- is also with a mech sander? If so, fast or slow?
6- same question except polish with what?

Thanks for your time

I know about letting the device do the work.
