airbrushing nail polish
Posted 25 September 2011 - 01:13 PM
That's really more details than my question requires but I am hoping for a lot of help. Is there some sort of hardener or accelerator in nail polish? I thinned it like other enamals and it kept acting like it needed more.
Can I spray the stuff without primer? I have not had good luck with this Testers primer at all. It pitted and created a surface that would have made this trip to the purple pond necessary no matter how good the polish went on. I thought I had inspected it well but the flaws were not obvious until the paint on.
Any help is appreciated. I thought this was going to be great (using polish) because I don't have a local hobby shop and hate to pay shipping when I need a little paint.

As far as spraying fingernail polish, i really can't help you there, as the one time I tried it, the results were not good. I wanted to do a Corvette in pearl white. At the time, the only pearl white available was nail polish. I thinned it using nail polish thinner, and proceeded to shoot t on my primed and white basecoated Corvette, which was originally molded in red. When it dried, i ended up with a horrible orangey color. That was caused by the solvents leaching the red from the plastic into the polish. Ended up giving the rest of the polish to my sister. Haven't tried it since.
Something I will suggest (this is what I do, as I too have no local hobby shop)is when you get a chance to go to a hobby shop, pe prepared to stock up. I usually go to Indy every other month or so for 1:1 car sows and swap meets, when I'm done there, I hit the local shops and stock up on anything I need, especially custom paint colors, but also resin casting and detail items. That way, i don't end up stuck should I need a certain color. Also, keep a watch for clearance paints. The local Wal-Mart cleared out their touch up paints (mostly Import colors) got a whole batch of it cheap, under a dollar a bottle.

Most nail polishes don't have a lot of pigment in them because they're ment to be applied way thicker than you would on a model so they tend to be rather transparent. Best way to fight this is to apply a similar color laquer, as close as you can get, under it as a base coat.
To keep all this from attacking the plastic is to apply a few coats of either BIN pigmented shallac or a good acrilic. Tamiya acrilic works for me but lots of people prefer Future floor finish for some reason.

I was careful to get enamals in the polish, so I will try thinning by 50% and see what I get.
I suppose I can still sand and wax like other enamels? There does appear to be a very slight metal flake in them.
