Hey everyone. Stopped by a house to look at some remodel work today. The drywall is all off, and I noticed that every place there was an electric line run, there was black tar seeping through the insulation exactly where the wires were. Looked like someone drew a line where each wire ran. All the insulation was tucked behind the wiring, so the wires where all on the facing of the insulation. Wondering if for some reason the wiring had at some point got hot and somehow heated up the tar that old insulation used to use to adhere the fiberglass to the paper and for some reason drew the tar through the paper. This house was hit by lighting years ago, so wondering if that may be the reason. Hopefully one of you had run across this. Thanks for any input.
