Repairing Piano Finish??

[jefe vt]

I have a set of nht m-100 speaks and the piano finish is chipped off in a couple of places. I was wondering if it is possible to fix this. An auto body guy suggested epoxy to fill in the space and then buff it out to a shine. "Kinda like a bowling ball" he claims?? I don't know if you have any other suggestions, but I am open to all.:scratch2:

Isn't a Piano Black finish multiple layers of black lacquer? If so, could you build it back up with a small brush and than sand it with progressively finer sandpaper?

I have the same issue with a couple corners on some black lacquer Thiel CS2.2's, but doubt that the finish is anything close to a true layered lacquer, these are speakers, not Steinways! In fact Theil suggested I could use Windex to clean mine, which suggests the outer 'gloss' is an enamel or epoxy. I'd be tempted to try auto-paint, but am open to other suggestions.

you could try fiber glassing them... may work

If it's truly a lacquer finish, a lacquer stick (and patience) would be the way to go. You'll need to dewax the areas and re-wax afterwards.
If it's a poly or epoxy finish you'll need the appropriate materials and again, patience to work the marred area up slowly.

They are the NHT m-100s and they seem to have almost a veneer, like a counter top. Not a true piano finish, I know. My father was a furniture refinisher, perhaps he could help me out with it.

If the chipped areas are small you could touch them up with fingernail polish. You might also check with auto dealers for touch-up paint.

Without going into great detail it would be pretty much the same as repairing a paint chip on a car. Like Mark B says you could probably use fingernail polish but finding a solid black for automotive chip repair might work better since it may sand out better once you get the chip filled with paint. Any auto parts store or dealership while have the touchup paint you need.

In the first link it says to let the paint dry for 24 hours but I would recommend filling the chips and letting them dry for a week before you try sanding them. The paint will feather edge better if you let it dry longer.

Also you must use a sanding block. Otherwise you will wear through the surrounding paint and not the area you just built up with paint.

Take your time and I'm sure you will have no problem with the repairs.

Better test whatever paint you use for compatibility before you put much on. If the original finish is lacquer, it may react with acrylic based paints.
