![]() I'm working on repairing a keyboard, there is trace damage on the membrane. So I got my little pen of silver conductive trace repair paint and repaired the trace. Let it completely dry, test it, and its not working. So I take my multimeter out, put it on continuity, touch 2 different area of the paint, and nothing. I put it on resistance, I get OL most of the time, occasionally it might flash to something ridiculous like 17 mega ohms or something.
Why is this stuff not working? This is what I am using https://www.amazon.com/gp/product/B00B88B9KI |

![]() Here is the data sheet for this part number
https://acct113328.app.netsuite.com/...1ddd7&_xt=.pdf Did you shake the tube for a while before you apply the product and did you let it dry for 24 hours before you checked the resistance You might have to do another layer of the product before you get the results that you are suppose to get I personally have not used the product before so I can only go by the data sheet You might want to get in touch with the company that made the product for technical support

I did read some people complaining that buying it from Amazon is a bad idea as this stuff loses potency the longer it sits and so it should always be purchased direct form the manufacturer. I will try picking up another tube and see if I can get this damn keyboard working |

![]() I tried a few more coats of the stuff, and tested it with my meter both wet and completely dry, and this shit isn't conducting anything. Luckily I saved the packaging, I'm sending it back. $33 and a lot of frustration for this garbage

![]() Just as a follow up I returned the garbage I had before and ordered the Chip Quik brand of conductive paint and it worked perfectly (https://www.amazon.com/gp/product/B07FBBBD87)
