Use regular nail polish and then, once it all dried and cured, a coat or two of acrylic.  But one thing to keep in mind is that not all nail polishes will work well with this technique.  Some nail polishes dry too fast and as a result do not let you swirl.  Others give you some working time but generally speaking, I think you have about 3 - 5 minutes to make your design and then apply it to your surface.  I did try to mix in some nitrocellulose lacquer retarder into one of the bottles to increase my working time but it caused the paint drop to sink to the bottom of the cup.

Does using different kinds of tubing from hearing aid tubing to like metal tubing actually change the sound. JH uses metal waive guides is this just for jacking the price up or is it real.

Dont know about JH, but different tubing does change sound.

I always assumed that the material wouldnt really change the sound and only the diameter.

Different material with different sound absorption ratio will change the upper mids-treble signature dramatically.

So if i went with maybe stainless tubing it might give it a brighter sound sig.

While it's very interesting technique it's not possible to do this on water or glycerin with acrylic UV curring material (for IEMs) it's too thick flowing and it sinks down in watter and barely keeps on glycerin.
Anyways you can do this on glass (like for faceplates making) but there's another problem - UV material mixes when you drop one on to another, but it's still possible to do.

Yes, that's true

So according to some article online, Teflon absorbs high frequency and is a good transmitter of low frequency?

Need some advice. What do you think about these three FR?
 
The flat

 
The bassy

 
The curvy

Pre-make the shells then use acrylic nail paint in water then coat with uv acrylic.

im gonna try this tomorrow night.

My daughter does this with her nails all the time. Some nail polishes are really thick and can be thinned out but not too thin so it still floats.

If you have problems with certain nail paint adhering to the shell buy some clear nail primer and use a thin layer on the shell. Dont ask why i know alot about nail paint lol.

How do you thin it? With nail polish remover?
