conformal PCB coating is hard to get in small volumes, expensive & may take weeks of delivery time. cosmetics clear nail polish re-tasked or used as protective coating for low voltage PCBs and audio electric coils. you can buy nail polish just about anywhere. |

Nail polish has been used for decades as adjustment locking paint. Unless it's porous, it shoold work okay as conformal coating. Acetone takes it right off. |

It would be cheaper to get some sort of lacquer from the local Home Depot. Perhaps someone has even evaluated which particular kind is the best for electronics? |

Moast Nail finish is nitrocellulose based. As such it it not very durable and likely to develope cracks after a few years. It is also highly flammable, not just liquid, but also when dry. I had some rosin based laquer that I used for protecting PCPs, so kind of non activated flux. |
