speaking of locktite I needed to get some last week and found some in Halfords that is like a lipstick, it's the blue stuff, I haven't seen this before, good idea I would think though as I generally waste a good bit of the liquid stuff as it either runs off the screw/nut or squishes out (yeah I know put less on)
I stumbled across the Loctite 'lipstick' recently like you. At first I was a bit sceptical so tested it on an innocent nut and screw. It worked so have used it since. One thought I have about it is that, unlike the liquid, I get the feeling that to ensure it doesn't get pushed off when doing up the nut or screw, I put it on the threads and push it down into the thread with my finger. Maybe I'm being over cautious since Loctite would have thoroughly tested it prior to making and selling it.
One thing in its favour is that you can actually see when you have nearly used up your supply to prompt you to get some more before the next job, avoiding finding that your little container of liquid Loctite is empty just when you need it (I bet we've all experienced that one).
