MG Chemicals Silver Print (Conductive Paint)

Very worst product

I used Tamiya masking tape on a rear screen, out of the car, to form 1.5mm wide channels and filled these with this product up to the copper tracks that still showed voltage and ensured a good 1cm overlap. The fumes were overwhelming, a respirator was no use and in a large open workshop, fully ventilated with a fan blowing across the work area, the fumes were unbearable, triggering an asthma attack and streaming eyes, the fumes hit anyone who walked through the building like a hammer and could be smelt two units away. I left the first two tracks to cure overnight and next day they showed no continuity across and carried no voltage whatsoever; basically lethal and utterly useless.

I had to use this on a speaker voice coil. It's a dual voice coil subwoofer and the leads were soldered under the dustcap, then covered in CA glue. So, uncovering that would have been quite a chore. I removed some of the paper over the coil leads running up the former and applied several coats of this. I don't measure any resistance. I then ran 1000 watts through the woofer just to see if this would burn like a fuse. It did not nor did it get warm. That makes sense given that it doesn't have any measurable resistance. I covered it with CA glue and that is a repaired woofer.

This product is not enough to do the shielding for the average electric guitar. It’s overpriced for the amount you get. Buy a spray can version where you get much more and application is faster with many coats if desired.

Conductivity is great, but very fast drying, to be used with extreme care as it is very expensive.

This works very well. Toothpick + MG Silver conductive paint= Very Happy RTX 3090 Founder's Edition (estimated about 460-525W new TDP at 100% power limit slider). Much easier than soldering. Functions like a 10-15 mOhm shunt resistor. Make sure you shake it vigorously before use. It can settle just like an aerosol can, so always shake it up to mix it well.
