What is the 'goop' referred to that you put on nuts/bolts to mark them in place after they are torqued? And where can I get some? I have looked around on several websites and asked in two separate hardware stores, and nobody seems to know what I'm talking about.
And you can get it in just about ANY color. I have white, purple, blue, and green. Orange is also a popular choice. My personal favorite is green, but purple is cool as heck too.
