Electrically Conductive Paint 50ml - Water-Based Carbon Coating for Guitar Shielding, PCB & Remote Control Repair - Matte Black EMI/RF Shield

Good for small electrical repairs such as worn pads - be aware that it has high resistance so it it won't work to repair long traces. Dries quickly.

I wanted to shield the control cavity of an electric guitar I’m putting together. I applied the paint and waited a few days. I’ve completed the wiring and grounded the painted sides of the cavity, creating a Faraday cage. It works in shielding the guitar from noise. But the paint hasn’t dried to a sealed surface, it has dried as a carbon particle powder. If I touch the sides of the cavity, I get black powder on my fingers. And it says on the container it’s a skin irritant. See picture of a white kitchen towel that I touched the surface with. And this is three days after painting. Not really suitable for my purposes. I will try a different shielding paint. You can get types that do dry completely to a sealed surface, this isn’t like that.

used to repair my second Netatmo exterior weather sensor, first one was replaced by Netatmo, this one is outside warranty. fully functioning again, lovely stuff

I was trying to electro plate in copper a 3D print of mine and it did not work very well, however this is not the products fault, more like my rudimentary knowledge of chemistry.

The paint quality is okay and dries quickly, but it might not be suitable for all purposes, as the paint is not durable enough for my needs because it doesn't stick for long. However, it is still good for most of the intended purposes. The bottle has enough paint to apply if it comes off. I also tested it on a TV remote, and it worked fine on the rubber one but did not properly stick on plastic.

I don't like that the bottle is shaped more like a hip flask so easy to topple over (don't tell me how I know), and also the consistency is quite liquid. This was used to shield an electric guitar and it took a few coats, but there's more than enough for many coats for a typical Strat body and from testing with a multimeter everything showed good connectivity. It is also easy to clean up afterwards with a bit of naptha, though I suspect the coating is going to be a bit fragile. But once under the pickguard it shouldn't move at all.

I used this to paint the membrane on a remote control as some of the buttons no longer responded. It does take a while for the paint to dry but once it has dried, the conductive paint worked as intended. Quite a big bottle, so I hope that it stays effective if I need to use this again in future.

This is just water and 'conductive carbon'. All carbon is conductive. It is way too thin and makes very high resistance PCB 'repairs'. Needs 10+ applications to get resistance below 10 ohms and the result is just carbon powder deposits that smear easily. And worst of all, you do not want to spill this stuff, but some idiot decided to put it in a bottle 10 times as tall as its narrowest base measure - Very easily toppled (I did it). Avoid this rubbish.
