how to remove the black gunk...
I have this black tar like patches that was used to hold large mirrors in my master bath. It looks like thye used white silicon caulk too. Any ideas on how to remove. So far I have had to rip the top paper off the sheetrock then dab drywall compound to fill and blend the texture in. Not the best but any ideas will help.
Please no one suggest to remove the entire area and replace with new sheetrock. I would rather cut off my manhood to have to blend in a entire wall of texture :D
